The midpoint of the diagonal of a a square is 4 units from the vertex of the square. Calculate (a) the perimeter of the square.
(b) the area of the square.

Below in bold.

Step-by-step explanation:

Let the sides of the square be x units long.

The length of the diagonal = 2*4 = 8 units ( as  the midpoint is 4  from vertex).

By Pythagoras:

x^2 + x^2 = 8^2

Solving for x:

2x^2 = 64

x^2 = 32

x = √32

=  4√2.

(a) Perimeter = 4 * 4√2

= 16√2 units.

(b) Area = (4√2)^2

= 16 * 2

= 32 units.

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
