Evaluate the expression c=-2.7
c+18 =?

Step-by-step explanation:

When c=-2.7, we substitute the value of c into the expression so we can add

c+18=-2.7+18=18-2.7=15.3

The shape of the sports field is a rectangle, so the area of the sports field is found by using the rectangle area formula: 

                                         .

We know the Area (6,450.35 square yards), and the length (90.85 yards). Substituting these in the formula we have:

                            .

Thus,  (yards).

71 yards
