Question

The lenght of a rectangle is five times its breadth. If the perimeter of the rectangle is 144 m , find the length and breadth of the rectangle

Answer 1

Answer: breadth is 12, length is 60.

Step-by-step explanation:

Length, l = 5 *b (breadth)

2l + 2b = 144

=> 2 (5b) + 2b = 144

=> 10b + 2b = 144

=> 12b = 144

=> b = 144/12

=> b = 12.

l = 5*12 = 60.

Answer 2

Answer:

12m and 60m

explanation:

let breadth of the rectangle to be=x

so, length of the rectangle to is = 5x

A.T.Q

2(length+ breadth)=perimeter reactangle

2(5x+x) = 144

10x + 2x= 144

12x= 144

x= 12

so,

length= 5(12) = 60 m

breadth= 12 m
