The answer is 50 feet.

Step-by-step explanation:

Heather is building a ladder for her tree house. She will need 13 feet of lumber for each stilt and 2 feet of lumber for each rung on the ladder.

Now, there are 2 stilts and 12 rungs.

And for 12 rungs, she needs feet of lumber.

Therefore, in total she needs:

=> feet

Hence, the answer is 50 feet.

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
