Question

The perimeter of a rectangle is 80 m. The length of the rectangle is 2 m less than 3 times its breadth. Find the length of the rectangle.

Answer 1

Step-by-step explanation:

80m=2(L+B)

80=2(3B-2+B)

6B-4+2B

8B=80-4

8B=84

B=84/8

B=12m

L=3B-2=3×12-2

L=34m

Answer 2

Let x = length of the rectangle Let y = the breadth of the rectangle Perimeter is 94 => 2x + 2y = 94 Divide both sides by 2; x + y = 47 The length of a
