Question

a scale drawing for an apartment is shown below.
in the drawing, 1 cm represents 5 m.
assuming the bedroom is rectangular, find the area of the real bedroom.
image of the apartment floor plan with living room (4 cm by 4 cm) and bedroom (2 cm by 3 cm)
area of the real bedroom: m²

Explanation:

Step1: Convert drawing width to real width

Real width = $2 \text{ cm} \times 5 \frac{\text{m}}{\text{cm}} = 10 \text{ m}$

Step2: Convert drawing height to real height

Real height = $3 \text{ cm} \times 5 \frac{\text{m}}{\text{cm}} = 15 \text{ m}$

Step3: Calculate real bedroom area

Area = $\text{width} \times \text{height} = 10 \text{ m} \times 15 \text{ m}$

Answer:

$150 \text{ m}^2$
