Some one please help me with this 3 part assigmant. I will give you as many points as you want. Just please do it correctly. Thank you.David and his dad were going camping. When they went into the garage to get their tent they noticed it was ripped. David’s dad said he could fix the tent. He would buy some new material to cover the one rectangular side that ripped.A) How much material does he need to cover one rectangular side of the tent? Justify your answer using equations/formulas, models, and/or words to explain your mathematical reasoning.Answer:B) If David’s dad wanted to re-cover the whole tent, how much material would he need? Justify your answer using equations/formulas, models, and/or words to explain your mathematical reasoning.Answer:C) If David found a roll of tent material in the garage that was 65 ft2, would he have enough material to cover the entire tent? Explain your reasoning.Answer:
Accepted Solution
A:
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.
