Question 17

A metal worker cuts two shapes: a rectangular plate and a triangular plate.

The rectangular plate has dimensions $(2 x + 8)$ cm by $(2 x - 3)$ cm. The triangular plate has side lengths of $(3 x + 4)$ cm, $(2 x + 5)$ cm, and $(2 x + 6)$ cm.

The total distance around the edge of the rectangle is the same as the total distance around the edge of the triangle.

Work out the value of $x$ .
