Question

The perimeter of a rectangle is 75 cm . Its length is 2 by 3/4 times its breadth . Find thr lenght and breadth of a rectangle​

Answer 1

Answer:

let breadth = x , then

length = 2* 3/4 * x = 3x/2

given ,

perimeter = 75 cm

or, 2(l + b) =75 cm

or, 2(3x/2 + x) = 75 cm

or, 2* 5x/2 = 75 cm

or, 5x = 75 cm

SO, x= 15 cm

Hence , breadth = 15 cm

& length = 15* 3/2 = 22.5 cm
