sergey [27]

The area  of Vivian’s garage door is 62.5 square feet

<h3>Area of composite shape.</h3>

The Vivian garage is made up of a trapezoid and a rectangle. The area of the door is expressed as;

Area = Area of rectangle + area of trapezoid

Area = (5 * 8) + 0.5(7 + 8)*3
Area= 40 +22.5
Area = 62.5 square feet

Hence the area  of Vivian’s garage door is 62.5 square feet

pishuonlain [190]
The relation between a and s is given to be:

a = 640s

where,

a = number of acres
s = number of square miles

We are to find the number of acres for 7.5 square miles.

This means, s = 7.5

Using the value in the formula, we get:

a = 640 x 7.5 = 4800 acres
