(05.02)a doghouse is to be built in the shape of a right trapezoid, as shown below. what is the area of the doghouse?
a right trapezoid with top side 5 feet and height 5 feet. the bottom side is extended to the right with 3 more feet.
32.5 square feet
40 square feet
187.5 square feet
375 square feet

The area of the doghouse is

Step-by-step explanation:

we know that

The area of trapezoid is equal to

where

b1,b2 are the parallel bases of trapezoid

h is the height of trapezoid

in this problem we have

substitute

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!
