Width: x
Length: 3x
Perimeter=x+x+3x+3x=8x
8x=400
x=50
Dimension is 150×50 feet (length × width)
5 wholes = 5
2 fifths = 2/5
5 - 2/5 = 4 3/5 (4 and 3 fifths)
Answer = 4 3/5
Check work:
4 3/5 + 2/5 = 5 (wholes)

Explanation:</h2>
Here we have the following expression:

So we need to extend this. Remember that the difference of squares tells us:

So here:

Thus:

Answer:
V= 42.41
