Question

the perimeter of rectangle is 90m and breadth is 25 m . the length is​

Answer 1

perimeter = 90

length = ??

breadth = 25

perimeter of rectangle = 2(l+b)

90 = 2 ( l + 25 )

90 ÷ 2 = l + 25

45 = l + 25

45 - 25 = l

20 = l

so, length of rectangle is 20

Answer 2

Answer:

length is 20m

Step-by-step explanation:

perimeter=2x(length + bredth)

So,

length=?

breadth=25m

perimeter=90m

A.T.Q.

Parimeter = 2(l + b )

90=2(l + 25)

90/2= (l + 25)

45= (l + 25)

45-25=l

20=l

l=20

Here (l) is equals to length and (b) is equals to breadth.
