Amy said, “the area of this figure is 60 square units.” This is her work. (4 x 10) + (2 x 2) + (2 x 2) + (2 x 6) 40 + 4 + 4 + 12 = 60 square units Amy is incorrect. Show what she did wrong and give the correct answer.

Her mistake is multiplying 12 inches by 13 so it will be 156 and than multiply 156 x 132. Her answer will be 20592.

Change the inches into feet. There are 12 inches in a foot so divide 144 by 12. That gives you 12, so then multiply 12 by 14. You are left with 168 feet.

The correct answer is:  [B]:  "Jesse is correct."

Note:

1  1  2,   5  1  2 acres
+ 2  1  8,   2  0 0 acres

3  3 0  , 7   1  2 acres .

The total is:  320, 172 acres.

Given:  "Jesse solved this problem. He said the area was 330,712 acres."

The measurements of a rectangular room are 13 feet by 132 inches.

We have to find the area of the room in square feet.

Area of rectangle with length 'l' and width 'w' is given by "$l \times w$".

Since, length='13' feet and width= '132' inches.

So, we will convert the unit of inches into feet.

As 1 foot = 12 inches

So, 132 inches = $\frac{132}{12}$ feet = '11' feet

Area of rectangular room = $13 \times 11$

= 143 square feet.

Tonya was incorrect because she evaluated the area of room without changing the dimensions. She found the area by $132 \times 13= 1716$ square feet. It is incorrect.

74.24 cm^2

Step-by-step explanation:

8 * 9.28 = 74.24 cm^2

To achieve the area of a circle, you must multiply pi times the radius squared. So in this case it would be ..
3.14 times 18.5 times 18.5.
Which is 1074.665 squared. Hope it help!

While Alexis is right in saying that 1/3 is greater than 1/6, she is NOT RIGHT in saying that the area of 1/3 of the trapezoid is greater than 1/6 of the hexagon.

We do not know the size (area) of these shapes. It could be that the trapezoid is terribly tiny and the hexagon is huge. The only way we can compare 1/3 of this to 1/5 of that is if the sizes of this and that are the same.

As an example, is eating 1/2 a pizza a lot? Well, whatever you believe about how much one should eat, the answer also has a lot to do with the size of the pizza. 1/2 of a personal pizza meant for one person is quite different that 1/2 of a large 8-slice restaurant-style pizza. What this means is that we cannot simply compare the fractions (1/3 and 1/6 or with the pizza 1/2 to 1/2), we have to keep in mind the areas (the size) of the figures (hexagon, trapezoid or whatever the pizza is...usually round) involved.

20,592 INCHES. First you have to take your 13 feet and times by 12 inches in a foot,, then take that total which is 156 inches times 132 inches to equal Area.
