Question

9. The length of a rectangular field is four times its
breadth. If the perimeter of the field is 900 m, find its
length and breadth.​

Answer 1

Answer:

Length= 360 m and Breadth= 90 m

Step-by-step explanation:

Let breadth of the field = b

Then length of the field, l = 4*breadth

l = 4*b

Now,

Perimeter of the field = 2(l+b)

900 m = 2*(4b+b)

900 m = 2*5b

900 m = 10b

b = 900/10 m

b = 90 m

So,

l = 4b = 4*90 = 360 m
