Answer:

Answer 1

The complete question in the attached figure
A) How much material does he need to cover one rectangular side of the tent?
to cover the rectangular side ABCD, calculate the area
Area=CD*AC=9*6=54 ft²
the answer part A is 54 ft²

B) If David’s dad wanted to re-cover the whole tent, how much material would he need? 

the area total=2*[Area ABCD]+2*[Area ACE]

Area ABCD=9*6=54 ft²
Area ACE=(1/2)*7*6=21 ft²
the area total=2*[54]+2*[21]=150 ft²

the answer part B is 150 ft²

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.

to cover the entire tent is required 150 ft²
150 ft²> 65 ft²------> David not have enough material to cover the entire tent

the answer part C is 
David not have enough material to cover the entire tent
