Question

The perimeter of a rectangle is 140cm. If the breadth of the rectangle 20 c, find length

Answer 1

Answer:

Step-by-step explanation:

Given

Perimeter of rectangle= 140 cm

We know that

Perimeter of rectangle= 2(l+b) where l= length of rectangle and b= breadth of rectangle

Also given b= 20cm

2(l+20) =140

l+20=70

l=70-20

l= 50cm

Therefore length of rectangle=50cm

Hope this helps u mate....

Answer 2

perimeter of rectangle=140cm

breadth of rectangle=20cm

length of rectangle=?

we know,

p=2(l+b)

140=2(20+l)

140÷2=20+l

70=20+l

l=70-20

l=50
