Question

jazlyn wants to purchase a triangular... ( a = \frac{1}{2}bh )
what are the actual base and height of the trampoline?
actual base = 10 ft
actual height = 12 ft
what is the actual area of the trampoline?
( square ) ft²
an error has occurred. please enter a number.
(diagram: triangle with height 3 in, base 2.5 in, scale 1 in. : 4 ft)

Explanation:

Step1: Recall the area formula for a triangle

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

Step2: Identify the values of base and height

From the problem, the actual base \( b = 10 \) ft and the actual height \( h = 12 \) ft.

Step3: Substitute the values into the formula

Substitute \( b = 10 \) and \( h = 12 \) into the formula \( A=\frac{1}{2}bh \). So we have \( A=\frac{1}{2}\times10\times12 \).
First, calculate \( \frac{1}{2}\times10 = 5 \), then multiply by 12: \( 5\times12 = 60 \).

Answer:

60
