Marty has a fenced yard in the shape of a triangle it's area is 635.4 ft.² The width of the yard is 18 feet what is the length of the fence

635.4 (ft) (ft) / 18 ft = 35.3 ft

Correct:

18 ft x 35.3 ft = 635.4 ft^2

Example:

In the problem, "if a square field has an area of 479ft squared, what is the approximate length of the side of the field".

The given is:

Area = 479 ft

Formula: Since to get the area you have to have length and width hence the formula of area which is:

Area = length x width

We can derive the equation. As length x area = area2

Solution:

Length = area2

Length = square root of 479 ft squared

Length = 21.9 ft"
