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. area of the real bedroom: □ m² (diagram shows living room 13 cm × 13 cm, bedroom 12 cm × 8 cm)

Explanation:

Step1: Find real length of bedroom

The scale is 1 cm = 5 m. The length of the bedroom in the drawing is 12 cm. So real length $= 12\times5 = 60$ m.

Step2: Find real width of bedroom

The width of the bedroom in the drawing is 8 cm. Real width $= 8\times5 = 40$ m.

Step3: Calculate area of bedroom

Area of rectangle is length $\times$ width. So area $= 60\times40 = 2400$ $m^2$.

Answer:

2400
