Question

The length and breadth of a rectangle are in the ratio 3:2.if its perimeter is 140 cm , find its dimensions

Answer 1

Answer:

length=3x

breath=2x

perimeter=140

2x+3x=140

5x=140

x=28

length=3×28=74

breadth=2×28=56

Answer 2

Answer:

Step-by-step explanation:

L=3x

B=2x

Perimeter of rectangle=2(l+b)

140 =2(3x+2x)

140 =2×5x

140 =10x

x =14

L=3×14

=42cm

B=2×14

=28cm
