See what you think, but the triangle figure I dont know how you would find the exact length of the sides of the triangle, but it is safe to assume that the length is 5.

so the perimeters 25 - 5 = 20

If the area of the square is 25 inches, each side is 5 inches because 5*5 = 25. If each side is 5 inches, can you figure out the total perimeter?

is it true that To get the perimeter of the square add up all the sides of the figure, so 3 sides of the square and 2 sides of the triangle

Gdeinward:

yes. so multiply those sides by 5.

The area of the square is 25 in^2; therefore, each side of the square is 5 inches in length. The base of the equilateral triangle is one side of the square, which makes the base and each side of the triangle equal 5 inches. The perimeter only includes the distance around the figure. P = 3 sides of the square + 2 sides of the equilateral triangle P = 3(5) + 2(5) P = 15 +10 P = 25 inches
