the actual length of a rectangular platform used for assembeling robots is 6 feet. in amal's drawing, the platform measures 1.2
saw5 [17]

Answer:

Actual width = 5 feet.

Step-by-step explanation:

The ratio of 1.2 to 1  equals the ratio of length to width.

1.2 / 1  = 6 / w  where w is the actual width.

1.2w = 6

w = 6/1.2

w = 5.
