Question

the perimeter of your school playground is 400 m the lenght is 3/2 times of that breadth. find the leght of the braedth

Answer 1

Answer:

80m

Step-by-step explanation:

Let breadth be m.

Let length be 3/2m.

Perimeter of rectangle = 2(l+b)

400 = 2(m+3m/2)

400/2 = (2m+3m)/2

200 = 5m/2

200*2 = 5m

400 = 5m

m = 400/5

m = 80 m

Thus, breadth = 80 m

         length = 120 m
