Answer:
The height of the garden will be 3 ft.
Step-by-step explanation:
Given;
area of trapezoid, A = 1/2(B+b)h
Where;
A is the area
h is the height
B is the big base
b is the small base
If; A = 27 ft²
B = 10 ft
b = 8 ft
h = ?
[tex]A= \frac{1}{2} (B+b)h\\\\27= \frac{1}{2} (10+8)h\\\\27*2 = 18h\\\\54 = 18h\\\\h = \frac{54}{18}\\\\ h = 3 \ ft[/tex]
Therefore, the height of the garden will be 3 ft.
