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?

 

You are very welcome!

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

25 inches
