Question

Two polygons are congruent and the perimeter of the first polygon is 24 cm. If the sides of the second polygon are consecutive integers (x, x+1, x+2, x+3, etc.), what value of x makes the polygons into congruent triangles?

Answer 1

x + x + 1 + x + 2 = 24

Answer 2

Congruent means same area, same perimeter, same side lenghts, etc. Therefore, the perimeter is also 24 and it's in 3 consecutive integers to form a triangle.

Answer 3

Just solve for x in the equation. \[x + x + 1 + x + 2 = 24\]

Answer 4

oh ok

Answer 5

Alright. What do you get for x?
