Area = 2831.25 square yards
Perimeter =215.6 yards
EXPLANATION
The area and perimeter of a rectangular field are found using the formula for finding the area and perimeter of a rectangle respectively.
That means, area of the rectangular field is given by the formula,
We just have to substitute
and 
into the given formula and evaluate.
This implies that;
This gives the area of the rectangular-shaped field to be;
square yards.
Now for the perimeter, we use the formula
Or
Substituting the values for the length and width gives,
Hence the perimeter of the rectangular shaped field is 215.6 yards.
Perimeter =215.6 yards
