Question

If the ratio of sides of 2 squares is 3:5, the ratio of their areas is 9:15

True or False​

Answer 1

False

Ratio for sides
=(L1):(L2)=3:5
Where L means length
Where L1 = 3 and L2=5

Ratio of area
=A1 : A2
Where Area=A=L x L = L2
Ratio of Area
= (L1)2:(L2)2
=(3)2 : (5)2
= 9 : 25
Hence the answer is 9 : 25 not 9 : 15

Answer 2

the answer is false, it is supposed to be 12:20
