A scale drawing of a rectangular park had a scale of 1 cm = 90 m.
8.1 cm
7 cm
What is the actual perimeter of the park in meters?
To find the actual perimeter of the park in meters, we need to convert the measurements on the scale drawing to the actual measurements using the given scale.
The scale is 1 cm = 90 m.
For the length of 8.1 cm:
Actual length = 8.1 cm x 90 m/1 cm = 729 m
For the width of 7 cm:
Actual width = 7 cm x 90 m/1 cm = 630 m
To find the actual perimeter, we add up the lengths of all sides:
Actual perimeter = 2(Actual length + Actual width)
= 2(729 m + 630 m)
= 2(1359 m)
= 2718 m
Therefore, the actual perimeter of the park is 2718 meters.
