Answer:
Step-by-step explanation:
<em>Look at the picture.</em>
We have
square with side length a = 9
trapezoid with base lengths b₁ = 9 and b₂ = 6 and the height length h = 6
right triangle with legs lengths l₁ = 3 + 6 = 9 and l₂ = 6
The formula of an area of a square
Substitute:
The formula of an area of a trapezoid:
Substitute:

Substitute:
The area of the shape:
See the attached figure
Let
h---------> building tall
we know that
tan 74°=h/34---------> h=34*tan 74°--------> 34*3.487------> 118.57
h=118.6 ft
the answer is h=118.6 ft
Let
