Question

The length of a rectangle is 20 cm more than its breadth. If the perimeter of the rectangle is 220 cm. Find the length of the rectangle and hence find the area of the rectangle

Answer 1

Answer:

Step-by-step explanation:

length=20+breath

perimeter2(l+b)=100

breath=x then

length =20+x then 2(2x+20)=100

2x=30

X=15 therefore length is 35 and breath is 15
