The figure is composed of a square with an equilateral triangle on top of it. If the area of the square is 25 square inches. What is the perimeter of the figure? A) 20 inches B) 25 inches C) 30 inches D) 35 inches E) 36 inches

bill533:

is it C

Gdeinward:

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.

bill533:

so the perimeters 25 - 5 = 20

bill533:

is that correct

bill533:

@dude

Gdeinward:

why did you subtract 5?

bill533:

i thought...

bill533:

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?

bill533:

@Gdeinward

bill533:

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.

Gdeinward:

that is what the image I posted represents

bill533:

it's C

Gdeinward:

no, its 25.

Gdeinward:

5 times 5

bill533:

oh sorry i did it wrong

bill533:

B. 25

Gdeinward:

correct. good job

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
