Question

Answer 1

She needs 50 feet of lumber.

Answer 2

The answer is 50 feet.

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.

So, for stilts she needs
`13*2` feet of lumber.

And for 12 rungs, she needs
`12*2` feet of lumber.

Therefore, in total she needs:

`(13*2)+(12*2)`

=>
`26+24=50` feet

Hence, the answer is 50 feet.
