Question

I'm really confused about this question

Answer 1

I think it is A:10ft

Answer 2

A. 10 ft

Explanation:

Since dimensions of the wall are similar to the dimensions of the window.

Therefore, lengths and widths of wall and window would be in proportion.

So,

`(h)/(2) = (24.5)/(4.9) \\ \\ h = (24.5 * 2)/(4.9) \\ \\ h = (49)/(4.9) \\ \\ h = (490)/(49) \\ \\ h = 10 \: ft`
