Question

jazlyn wants to purchase the triangular trampoline shown. the scale is shown in the drawing. 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? 80 $ft^{2}$

Explanation:

Step1: Identify base and height values

Given actual base $b = 8$ ft and actual height $h=10$ ft.

Step2: Apply area formula

Use the formula for the area of a triangle $A=\frac{1}{2}bh$. Substitute $b = 8$ and $h = 10$ into the formula: $A=\frac{1}{2}\times8\times10$.

Step3: Calculate the area

First, $\frac{1}{2}\times8 = 4$, then $4\times10=40$. So $A = 40$ ft². But there is a mistake in the original answer. The correct calculation is $A=\frac{1}{2}\times8\times10=40$ ft².

Answer:

$40$ ft²
