Land surveyors outlined a park as shown. What is the area of the park? Question 7 options:

70.88 km^2

76.95 km^2

83.03 km^2

184.68 km^2

Show your work:

Step-by-step explanation:

Dividing the shape into two:

The area of the rectangle is

A= 13.5*4.8= 64.8km2

the area of the triangle

A = [( 5.7-4.8) *13.5 ]/ 2= 6.075km2

Therefore the total area is

At = 64.8 + 6.075 = 70.875km2

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

true
