Answer:
20 units
Step-by-step explanation:
Let the equal sides of the triangle be x.
Then the third side will be (x+5) units
Since the perimeter is 50, we have:

We simplify to get:

This implies that:


Divide both sides by 3 to get:

The length of the third side is:
15+5=20
Answer:
a. 81 square inches
b. 108 inches
Step-by-step explanation:
The area of all 5 squares combined is 405 square inches. This is 5 times the area of 1 square. 405/5 = 81. The area of 1 square is 81 square inches.
Since this is a square, the sides are equal. Thankfully the area of 1 square is a perfect square so the length of one side of the square is a full number, which is 9. All of the squares are congruent as shown in the diagram so we simply add every length together (there are 12 sides, each side is 9 inches).
12*9 = 108 and that is the perimeter.
