Answer:
1 3/4 m
Explanation:
You want the length of a rectangle 4/5 m wide that has an area of 1 2/5 m².
Length
The formula for the area of a rectangle is ...
A = LW . . . . . . L = length; W = width
Filling in the given values and solving for L, we have ...
1 2/5 m² = L(4/5 m)
L = (7/5 m²)/(4/5 m) = 7/4 m = 1 3/4 m
The length of the rectangle is 1 3/4 meters.
