Question

A rectangle has a perimeter of 50cm and breadth of 10cm calculate its length

Answer 1

Answer:

We know that

perimeter=2(l+b)

given perimeter =50cm

and width=10cm

length=?

50=2(l+10)

25=l+10

l=25-10

l=15 ans

Answer 2

Step-by-step explanation:

2 (l+b)=50

2 (l+10)=50

l+10=50/2

l+10=25

l=25-10

l=15
