Question

The length of a rectangle is 5times more than its breadth and its perimeter is 240. Find its length and breadth​

Answer 1

Answer:

L=5B

2(L+B) = Perimeter

2(5B+B)=240

2 x 6B = 240

12 B = 240

B= 240/12

Breadth= 20

Length= 5 B => 5 x 20 => 100

Step-by-step explanation:

Answer 2

Answer:

L=5B so2(L+B)=2(6B)=12B= 240soB=240/12=20 SO L=5×20=100
