Question

Work out the ratio of AREA of Rectangle A to Rectangle B in the simplest form.

Multiple choice :
A.) 5 : 3
B.) 3 : 4
C.) 4 : 9
D.) 4 : 11

Answer 1

C

Explanation:

Given ratio of sides = a : b , then

ratio of areas = a² : b²

Here

ratio of sides = 16 : 24 = 2 : 3 , then

ratio of area = 2² : 3² = 4 : 9 → C

Answer 2

C.) 4:9

Explanation:

`10*16=160\\24*15=360\\160:360=4:9`
