Answer 1

Given : Elena's bed measures 4 cm by 3 cm on the scale drawing

The ratio is 1 to 50

To Find : ACTUAL measurements of her bed

Solution:

ratio is 1 to 50

=> 1  unit on drawing = 50 unit of actual

=> 1  cm on drawing = 50 cm of actual

Elena's bed measures 4 cm by 3 cm on the scale drawing

4 cm on drawing = 4 x 50 = 200 cm of actual

3 cm on drawing = 3 x 50 = 150 cm of actual

100 cm = 1 m

=> 4 cm on drawing = 2 m of actual

3 cm on drawing = 1.5  m of actual

ACTUAL measurements of her bed = 2 m by 1.5 m
