Answer:
Base of the ladder is 3 meters away from the building.
Step-by-step explanation:
Let's use Pythagoras theorem to solve.
Pythagoras theorem says,
Here let horizontal distance is "a''
Vertical distance of window is 4 m
So, b=4
The Rafi leans 5 m ladder against the wall. So, c=5.
Simplify it
Subtract both sides 16
Take square root on both sides
a=±3
So, base of the ladder is 3 meters away from the building.

<u>Answer:</u>
<h2>
A = 64.5 in²</h2>
<u>Steps:</u>
A = 13 × 6.5 - ((4 × 3×2)-2²)
A = 84.5 - (24 - 4)
A = 84.5 - 20
A = 64.5 in²
