25/12.5 = 40/y
cross multiply
(25)(y) = (12.5)(40)
25y = 500
y = 500/25
y = 20 <====
Here too same procedure
4) 156 is the answer
Answer:

Step-by-step explanation:
If we draw a right triangle, it would have legs 6 and 2.
The total area is 625 because 25 x 5 = 125. 125 x 5 = 625. that is how you get your answer
