Question

the sides of a rectangular piece of paper are in ratio of 2:3.if the area is 150 sq cm find the length of its sides​

Answer 1

Step-by-step explanation:

Let the common multiple be x,

So the sides will be 2x and 3x.

Area of a rectangle = length × breadth

Given,

A = 150 sq cm

Therefore,

150 = 2x × 3x

150 = 6x^2

x^2 = 25

x = 5

Thus,

the sides are 10cm and 15cm.
