Question

the side of rectangle are in the ratio 2 : 3 find its side if its perimeter is 20 CM​

Answer 1

let the sides be 2x and 3x

Perimeter of rectangle = 2(l+b)

According to the question :-

2(2x+3x) = 20

2× 5x = 20

10x = 20

X = 20/10

X = 2

Side of rectangle :-

2x = 2×2 = 4 cm

3x = 3×2 = 6 cm
