Question

1. In a triangle ABC, side AB is x cm, side BC is five more than side AB, and side AC is two times side BC. If the perimeter is 41 cm, find the value of x and each side.
2.  A rectangle has a length one more than two times its width. The perimeter is 44 inches. Find the dimensions of the rectangle.

Answer 1

x+ 5+x + 2(5+x) = 41

4x = 41-15 =26

x = 6.5

AB = 6.5

BC = 11.5

AC= 23
