A=LxW
L=12
W=8

12x8=96ft. 
Area = 96ft (without the window.)

Now we need to subtract the window from the area from the wall. What is the area of the window?

A=LxW
L=4
W=4

4x4=16
A=16ft (Area of just the window)

Let's subtract the window form the wall to get the total area!

96-16=80ft

A=80ft

tatiyna
To prove that jill is wrong we just need an example of this;


2*3*5*7*11*13 = 30030 (this is the smallest number with 6 different prime numbers)

5953*5981*5987 = 2.13x10^11 (which is obviously a much bigger number)

this is enough to prove that jill is wrong

Find the area of the shaded region.
Citrus2011 [14]

Answer:

pi × 18cm^2

Or approximately,

56.52cm^2 (using 3.14 for pi)

or

56.5487cm^2 (using pi button on calculator)

Step-by-step explanation:

Area of a circle is pi times [radius squared].

All circles are 360°.

Problem can be solved by finding area of whole circle, and then using ratios.

Whole Circle: area = pi × (9cm)^2 = pi × 81cm^2

80° / 360° = Area[shaded] / (pi × 81cm^2)

pi × 18cm^2 = Area[shaded]

((If you read my answer before the edit, I am sorry. I made a calculator error.))
