Answer:

What you need to find is the extra amount of plywood. To do that, you must find the area of the square and the area of the circle and subtract them to find the answer.

Explanation:

Formulas:

area of a square: A = bh

area of a circle: A =

square measurements:

b = 28

h = 28

circle measurements:

(≈3.14)

r = 14

A = (28)(28)

A = 784

area of square = 784 in^2

A = 3.14 ()

A = 3.14 (196)

A = 615.44 in^2

784 - 615.44 = 168.56

The amount of plywood left over is 168.56 in^2.

Hope this Helps.
