Question

angle = \frac{1}{2}bh
he actual base and height of
line?
= 8 ft
t = 10 ft
actual area of the trampoline?
1 in.:2 ft

Explanation:

Step1: Find actual base

Since the scale is 1 in. : 2 ft and the drawn - base is 4 in., multiply the drawn - base by the scale factor.
$4\times2 = 8$ ft

Step2: Find actual height

Since the scale is 1 in. : 2 ft and the drawn - height is 5 in., multiply the drawn - height by the scale factor.
$5\times2=10$ ft

Step3: Calculate actual area

Use the area formula for a triangle $A=\frac{1}{2}bh$, where $b = 8$ ft and $h = 10$ ft.
$A=\frac{1}{2}\times8\times10=40$ square feet

Answer:

40 square feet
