Question

Calculate the ratio of areas of two square fields of side measuring 20 metres and 25 metres, respectively.

• A. 16:25
• B. 3:2
• C. 4:5
• D. 12:15

Answer 1

The correct option is A 16:25

Side of first square = 20 metre

Area of the first square = $20\times 20$ $metr{e}^2$ = 400 $metr{e}^2$

Side of second square = 25 metre

Area of the second square = $25\times 25$ $metr{e}^2$ = 625 $metr{e}^2$

Therefore, ratio = 400 : 625 = 16:25
