Question

In a parallelogram one side is 5x-4 and the consecutive side 2x+3.If the perimeter is 166cm,find the lengths of the sides.

Answer 1

5x - 4 = 56

2x + 3 = 27

Explanation:

2(5x - 4 + 2x + 3) = 166

10x - 8 + 4x + 6 = 166

14x - 2 = 166

+ 2 +2

14x = 168

divide both sides of the equal sign by 14

12

5(12) - 4 = 60 - 4 = 56

2(12) + 3 = 24 + 3 = 27
