Question

area of triangle = \\(\frac{1}{2}bh\\)\
what are the actual base and height of the trampoline?\
actual base = ? ft\
actual height = ? ft\
(image of a triangle with base 4 in, side 5 in, and scale 1 in : 2 ft)

Explanation:

Step1: Identify scale factor

Scale: $1\ \text{in.} = 2\ \text{ft}$

Step2: Calculate actual base

Actual base = $4\ \text{in.} \times 2\ \frac{\text{ft}}{\text{in.}}$
$\implies 4 \times 2 = 8\ \text{ft}$

Step3: Calculate actual height

Actual height = $5\ \text{in.} \times 2\ \frac{\text{ft}}{\text{in.}}$
$\implies 5 \times 2 = 10\ \text{ft}$

Answer:

Actual base = $8$ ft
Actual height = $10$ ft
