Area of a rectangle = length times width.
Here, the area is (5 yd)(4 yd) = 20 yd^2. We must convert this into ft^2:
20 yd^2 3 ft
------------ * { ----------- }^2
1 1 yd
The comes out to (20)(3)^9, or 180 ft^3, the area in square feet.
The answer is 180 ft^2.
5 yards = 15 feet
4 yards = 12 feet
15*12 = 180 ft^2
