Answer 1

Hey I know how to do this. For future people.

Step-by-step explanation: The first part the answer is 54 because 6*9=54.

The Second Part is 213 not 150 because 108+42+63=213 (63 is the bottom rectangles area 7*9=63)

The third part is no he wouldnt have enough 65<213.

Hope this helped!! (^3^)

Answer 2

Okay. For the first part, lets say the area = x. SO the area of the rectangular side is x = 9 times 6. SO x = 54. :) Area (or x) always equals length times width, so it would be 9 times 6.


For the second part, you have to find the areas of each face of the tent individually and then add them together. So first, lets take the triangular sides of the tent. We can find the area of them combined if we multiply by 2.


SO your formula would be... 2(1/2 times 7 times 6). That is equal to 42.
Then for the rectangular sides, 2( 9 times 6). That is equal to 108.
So add those together. 42 + 108 = 150. So they would need 150 square feet of tent to recover the whole tent.


For the third part, the answer is no. 150 > 65. There would be 95 feet of tent more needed to cover the tent.


Okay, I hope this helps!!!!!!
