Answer:
The area of the rectangle is 196 ft^2.
Explanation:
Looking for: Area
The length of a rectangle is four times its width can be translated into
l = 4w
Perimeter = 2w + 2l
2w + 2(4w) = 70
2w + 8w = 70
10w = 70
w = 7
l = 4w
l= 4(7)
l=28
Area = l times w
28 times 7 = 196
The area of the rectangle is 196 ft^2.
