Question

“These figures are similar. The area of one is given. Find the area of the other.”

Answer 1

100 inch²

Explanation:

Two similar figures have been given in the figure

Ratio of the corresponding side =
`(15)/(21)= ((5)/(7))`

As we know area is two dimensions unit or it is a multiplication of two sides.

So square of ratio of the sides = ratio of their areas.

`((5)/(7))`² =
`((x)/(196))`

`x=(196* 25)/(49)` = 100 inch²

The area of other figure is 100 inch²
