Question

Find the dimensions of a rectangle if its perimeter is100 cm and its length is20cm more than its breadth​

Answer 1

Answer:

given that length=x+20 and breadth=x

Step-by-step explanation:

perimmeter =2(l+b)

2(l+b)=100

2(x+x+20)=100=

(2x+20)=100/2

(2x+20)=50

2x=50-20=30

x=30/2

x=15

breadth=15

length= 15+20=25
