Question

Rectangle length=20, perimeter=100 find out width​

Answer 1

Answer:

2(l+b) = 100

2(20+b) = 100

40+2b= 100

2b = 100-40

2b= 60

b = 60/2= 30

b=30

breadth means width so,

width=30m answer

Answer 2

Step-by-step explanation:

solve for widht

w=30

length= 20

perimeter= 100

using the formula

p =2 ( l + w )

solving for w

w = p/2 - l = 100/2 - 20 = 30 .
