Question

sides of a rectangle are in the ratio 2:3 find its perimeter if
its area is 150cm square

Abhigyan Dey · Accepted Answer

Let length and breadth are 3x and 2x respectively
According to question -
Area of Rectangle = Lenghth X Breadth
=> 150 = 2x * 3x
= 6x2 =150
=> x2 =25
x= 5
Thus, Length = 3*5= 15cm and breadth =2*5 = 10cm
Perimeter = 2(length+ breadth)= 2( 15+10)= 50cm
