Question

The perimeter of a rectanglar field is 334 yards. If the widths the field is 78 yards, what is its length

Answer 1

The length of rectangular field is 129 yards.

Explanation:

Given that

Perimeter = P = 334 yards

Width = w = 78 yards

Length = l = ??

We will use the perimeter of the formula to find the length of rectangle.

The perimeter of a rectangle is given by:

`P = 2(l+w)`

Putting the values of perimeter and width

`334 = 2(l+38)\\334 = 2l+76\\334-76 = 2l+76-76\\258 = 2l\\(2l)/(2) = (258)/(2)\\l = 129`

Hence,

The length of rectangular field is 129 yards.
