Question

the difference between lenght and breadth of 8cm and perimeter is 64cm.find lenght and breadth of rectangle.​

Answer 1

Answer:

Length = 20 cm, Breadth = 12 cm.

Step-by-step explanation:

Let Length and breadth be L and B.

Given,

L - B = 8  -------------- [1]

Perimeter of rectangle = 64

=> 2(L+B) = 64

=> L+B = 32 ---------------- [2]

Solve [1] and [2] by adding both equations

L -B = 8

L + B = 32

---------------

2L = 40

=> L = 20

=> B = 12
