Answer:
62
Step-by-step explanation:
3 x 5 = 15
3 x 2 = 6
2 x 5 = 10
15 x 2 = 30
6 x 2 = 12
10 x 2 = 20
30 + 12 + 20 = 62

x = 3 because the 2 legs of 45-45-90 triangle are equal
y^2 = 3^2 + 3^2 = 18
y = sqrt 18 = 3 sqrt2
Answer: The answer is 117
Step-by-step explanation:
This is because the triangles are both 18 cm^2 and the square is 81 cm^2. You add 36 and 81 to get 117.
