Answer :

Answer:  Yes, the house is 12 m tall.

Step-by-step explanation:

Since the two triangles are similar, you can set up a proportion.

Like:  [tex]\frac{x}{8.8}= \frac{1.5}{1.1}[/tex]   (other proportions could be correct, as long as corresponding parts are lined up).

Solve by cross-multiplying (multiply each diagonal, then set equal).

This gives us:     1.1(x)  = 8.8(1.5)

Simplify:                 1.1x = 13.2

then divide both sides by 1.1 to solve for x:   x = 13.2/1.1 = 12

This tells us the height of the house is 12 m.  A 13 m ladder would ideally reach the top.
