Question

On a scale drawing, the scale factor is 1/12. A plum tree is 7 inches tall on the scale drawing. What is the actual height of the tree

Answer 1

84 in . . . or . . . 7 ft

Explanation:

The given scale is the ratio of drawing size to real size.

1/12 = (7 in)/(actual height)

Multiplying this equation by 12(actual height) gives ...

actual height = 12·7 in

actual height = 84 in = 7 ft
