Question

The measure of two adjacent sides of a rectangle are in the ratio of 11:10.If the perimeter of the rectangle is 84 cm,find its area?

Answer 1

Hi there✋✋,

Here's the answer:-

Let the sides be 11x and 10x

Perimeter = 2(11x + 10x) = 2(21x) = 42x

=> 42x = 84

=> x = 2

So,

The sides are 22 and 20 respectively.

Area = l×b = 22× 20 cm² = 440cm²

HOPE IT HELPS ☺

Answer 2

Let the two adjacent sides are 11x&10x.
Perimeter =2 (11x+10x)
=2×21x
=42x
Perimeter =84cm (given )
42x=84
x=2cm
so,Length =11×2=22cm Breadth =10×2=20cm

Therefore, Area=Length ×Breadth
= 22×20=440cm^2
