How do you find the surface area of similar figures?

To find the surface area of similar figures, you first need to determine the scale factor between the two figures. If the scale factor is ( k ), then the ratio of their surface areas will be ( k^2 ). Multiply the surface area of one figure by ( k^2 ) to find the surface area of the similar figure. This principle applies to any pair of similar shapes, regardless of their dimensions.

Two similar polygons have perimeters of 10 miles and 20 miles and the area of the larger is 300 miles find the area of the smaller?

In similar figures, any unit of area is proportional to the square of any linear measure. In this case, since the perimeter of the larger figure is twice as big, the area of the larger figure will be 4 times as big.


How do you find the perimeter and area of a composite figures?

Break the composite shape down into simple units. Find the perimeter and area of each and then add these up as appropriate. If the shape cannot be broken down easily you may have to rely on integration or numerical methods.


How do you find the area ratio and perimeter of two corresponding sides of two similar polygon?

To find the area ratio of two similar polygons, you square the ratio of their corresponding side lengths. If the ratio of the sides is ( r ), the area ratio will be ( r^2 ). The perimeter ratio of two similar polygons is simply the same as the ratio of their corresponding side lengths, ( r ). Thus, if the side length ratio is known, both the area and perimeter ratios can be easily calculated.
