To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

Remember the formulas for both area and perimeter of a square. The area of a square is a = s 2, or side times side, while the perimeter is p = 4s, or 4 times s.

To find the surface area, the amount of space on the outside of a solid, of a trapezoidal prism, you'll need to find the area of the trapezoid base and multiply it by two. You'll then add the area of the four rectangles to the area of the two bases.

Use the formula r = √(A/(4π)). The surface area of a sphere is derived from the equation A = 4πr2. Solving for the r variable yields √(A/(4π)) = r, meaning that the radius of a sphere is equal to the square root of the surface area divided by 4π.

The same is true for a square, but there's a key difference: For a square, the length and width are equal. If the length is L, then the area of the square is L2. If you know the area of the square, you can immediately calculate the length of each of its sides by rearranging the above equation: L = √A.

How to find the surface area of a square pyramid using the formula? Surface area = 2bs + b2 where b is the length of the base and s is the slant height. Examples: What is the surface area of a square pyramid with a base area of 255 square inches and a height of 7 inches?

Measure the radius of the circle. Multiply the radius by the radius. For example, if you have a 18 inch radius, you would multiply 18 inches by 18 inches to get 324 square inches. Multiply the step 2 result by 3.1415, an approximation of pi, to find the circular area.

The area is measurement of the surface of a shape. To find the area of a rectangle or a square you need to multiply the length and the width of a rectangle or a square. Area, A, is x times y.

For squares, multiply one side by itself to get the area. If you have a parallelogram, multiply the diagonals and divide by 2 to get the area. To find the area of a trapezoid, add the base and the height together, and divide that number by 2 times the height.

To work out the area of a square or rectangle, multiply its height by its width. If the height and width are in cm, the area is shown in cm². If the height and width are in m, the area is shown in m². A square with sides of 5 m has an area of 25 m², because 5 × 5 = 25.

The surface area is the number of square units that fit into the square. As shown in the picture, the surface area of this square is 16 total square units.

To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

['Volume = πr2h.', 'Top Surface Area = πr2', 'Bottom Surface Area = πr2', 'Total Surface Area. = L + T + B = 2πrh + 2(πr2) = 2πr(h+r)']

Add the six areas together. Add them all together to get the area of the whole shape: lw + lw + wh + wh + lh + lh. You can use this formula for any rectangular prism, and you will always get the surface area. To finish our example, just add up all the blue numbers above: 12 + 12 + 15 + 15 + 20 + 20 = 94 square inches.

The formula to find the surface area of a rectangular prism is A = 2wl + 2lh + 2hw, where w is the width, the l is the length, and the h is the height. To use this formula, we plug in our values and then evaluate.

For a square-based prism with a given volume, the minimum surface area occurs when the prism is a cube. Given a volume, you can find the dimensions of a square-based prism with minimum surface area by solving for s in the formula V = s3, where V is the given volume and s is the length of a side of the cube.
