Question

Write an equation to determine the value of x so that each pair of polygons has the same perimeter. Then solve

Answer 1

Explanation:

Answer 2

Explanation:

15). Perimeter of both the polygons are same.

Sum of the sides of the triangle = Sum of the sides of the rectangle

Therefore, the equation will be,

(x + 6) + (x + 9) + (x + 3) = 2(x + 1) + 2(x + 4)

16). Sum of the measures of all sides of the hexagon = sum of all sides of the triangle

Therefore, the equation will be,

6(5x) = (x + 14) + (x + 17) + (8x + 9)
