Question

The perimeter of a rectange is 48cm length is 3 more than twice the breadth.Find the legth and breadth​

Answer 1

Answer:

Length = 17cm

Breadth = 7cm

Step-by-step explanation:

Perimeter = 2(l + b) = 48cm; where l = length and b = breadth.

Given l = 3 + 2b

∴Perimeter = 48cm = 2(3+2b + b)

2(3+3b) = 48cm

3(1+b) = 48/2 = 24

1 + b = 2v/3 = 8cm

b = 8 - 1 = 7cm

Breadth = 7cm//

l = 3 + 2b = 14 + 3 = 17cm

Length = 17cm//
