Answer:
55 meters
Explanation:
The length in meters is found by converting the units from feet to meters. The length in feet is found by computing the perimeter of a rectangle with the given dimensions.
__
perimeter
The formula for the perimeter of a rectangle is ...
P = 2(L +W)
For a rectangle with length L = 56 ft and width W = 34 ft, the perimeter is ...
P = 2(56 ft +34 ft) = 2(90 ft) = 180 ft.
__
units conversion
Each foot is 0.3048 meters. Multiplying that length by the number of feet gives the number of meters.
180(1 ft) = 180(0.3048 m) = 54.864 m
