Question

/ The length of rectangle is 2 cm more than twice its breadth. Perimeter of the rectangle is 82 cm. Find its length and breadth. *​

Answer 1

answer

length= 28cm

breadth=13cm

Explanation:

let, length and breadth, L and B.

Thus L = 2B + 2

Also perimeter P = 2(L + B)= 82

Substitute the first equation into the second and get

2(2B + 2) + 2B = 82

4B + 4 + 2B = 82

6B + 4 = 82

6B = 78

B = 13

L = 28
