Question

area of triangle = (\frac{1}{2}bh)
what are the actual base and height of
the trampoline?
actual base = 8 ft
actual height = 10 ft
what is the actual area of the trampoline?
(square) ft²
(diagram: triangle with 5 in. height, 4 in. base, scale 1 in. : 2 ft)

Explanation:

Step1: Recall the area formula for a triangle

The formula for the area of a triangle is \( A = \frac{1}{2}bh \), where \( b \) is the base and \( h \) is the height.

Step2: Identify the actual base and height

From the problem, the actual base \( b = 8 \) ft and the actual height \( h = 10 \) ft.

Step3: Substitute the values into the formula

Substitute \( b = 8 \) and \( h = 10 \) into \( A = \frac{1}{2}bh \):
\[
A = \frac{1}{2} \times 8 \times 10
\]

Step4: Calculate the area

First, calculate \( \frac{1}{2} \times 8 = 4 \), then \( 4 \times 10 = 40 \).

Answer:

40
