Answer:
1.5 m by 90 m
Explanation:
Recall that the formula for the area of a rectangle is A = L * W.
Here, the area is given: A = 135 m^2, and this area is the product of the length and width of the rectangle: 135 m^2 = (1.5 m)(W), where W is the side of unknown length.
Solving for W: W = (135 m^2) / (1.5 m) = 90 m
Thus, the dimensions of the floor are 90 m by 1.5 m.
