Question

The breadth of a rectangle is two -thirds of its length If the perimeter of the rectangle is 135cm find dimensions of the rectangle​

Answer 1

Answer:

Let the length and breadth if the rectangle be 'l' and 'b' respectively.

According to the question,

b= 2l/3

perimeter = 135 cm

=> 2(l+b) = 135

=> 2( l+2l/3) = 135

=>2(5l/3) = 135

=>10l/3 = 135

=> 10l = 135*3

=> l = 405/10

=> l = 40.5

b = 2l/3

b = 2*40.5/3

b = 81/3 = 27

Therefore, the length and breadth of the rectangle is 40.5 cm and 27 cm respectively.
