Faron wants to paint the four walls in his bedroom. The room measures 12 ft long, 10 ft wide and 8 ft high. There are two doors
Rainbow [258]

Answer:

319 square feet.

Step-by-step explanation:

The walls of the room (the ones on the long side) have an area of 12 x 8 = 96 square feet each one. Thus, their area is 96 x 2= 192 square feet.

The other two walls have an area of 10 x 8 = 80 square feet each one. Thus, their area combined is 80 x 2 = 160 square feet.

Therefore, we have that the total area of the four walls is

192 +160 = 352 square feet

However, we have a door and a window that won't be painted.

The area of the door is: 3 x 7 =21 square feet

The area of the window is 3 x 4 = 12 square feet

Thus, the total amount of area that won't be painted is

21 + 12 = 33 square feet.

So we are going to take the total area minus the area that won't be painted to know the total area that Faron will pain:

352 - 33 = 319 square feet.

Thus, she will paint 319 square feet

What is the total area of the figure? Please help I’ll give brainliest!!
GalinKa [24]

Answer:

64 square inches

Step-by-step explanation:

You can split this figure into a rectangle and triangle to find the area.

A= l * w

A= 5 * 12

Area of the rectangle = 60 sq in

A= 1/2 bh

b= 12-8     = 4

h= 7-5       =2

A= 1/2 (4)(2)

Area of the triangle = 4 sq in

60 + 4 = 64 sq in
