Question

a plot of land is in the shape of a triangle. if one side is x meters, a second side is (2x - 3) meters and a third side is (5x - 5) meters, express the perimeter of the lot as a simplified expression in x.
the perimeter of the lot is ( ) meters.

Explanation:

Step1: Recall perimeter formula

Perimeter of triangle = sum of sides. So, $P=x+(2x - 3)+(5x - 5)$.

Step2: Remove parentheses

$P=x + 2x-3+5x - 5$.

Step3: Combine like - terms

$P=(x + 2x+5x)+(-3 - 5)=8x-8$.

Answer:

$8x - 8$
