A landscape artist makes a scale drawing of a public garden. The scale used is 1 cm to represent 10 m.
a. The width of the garden on the scale drawing is 18.2 cm. Calculate its real width. 1 cm represents 10 m, so 18.2 cm represents 18.2 × 10 = 182 m. The real width is 182 m.
b. The length of the actual garden is 425 m. Calculate its length on the scale drawing. 10 m is represented by 1 cm, so 425 m is represented by 425 ÷ 10 = 42.5 cm.
The length on the drawing is 42.5 cm.
