Question

A scale drawing for an apartment is shown below.

In the drawing, 3 cm represents 5 m.
Assuming the bedroom is rectangular, find the area of the real bedroom.

Answer 1

150 sq.m or m^2

Explanation:

Area of rectangel = l x b

Breadth in the given scale = 6cm = 3+3 cm

Breadth in true scale = 3x5+3x5 = 10m

In that sense,

Length in true scale = 15m

Area of the bedroom = 15 x 10 = 150 sq. m

Answer 2

150m²

Explanation:

Scale:

3cm represents actual 5 m(3:5)

Real bedroom

length 9 cm which is 15m

width 6 cm which is 10m

both using the relation ratio

thus,

A = L×W

A = 15 m ×10 m

A = 150m²
