Question

The sides of two squares are in the ratio 5 : 7. Find the ratio of their areas.

Answer 1

Let side of first square = $5x$

And, side of second square = $7x$

Therefore,

Area of first square = $25x^2$

And, area of second square = $49x^2$

Ratio of areas = $\frac{25x^2}{49x^2}=\frac{25}{49}$
