Card 1 of 16
Cassie is making a kite for her little brother. She has two plastic tubes to use as the skeleton, measuring 
inches and 
inches. If these two tubes represent the diagnals of the kite, how many square inches of paper will she need to make the kite?

To find the area of a kite, use the formula 
, where 
represents one diagnal and 
represents the other.
Since Cassie has one tube measuring 
inches, we can substitute 
for 
. We can also substitute the other tube that measures 
inches in for 
.

To find the area of a kite, we will use the following formula:
where p and q are the lengths of the diagonals of the kite.
Now, we know the length of one diagonal is 18in. We also know the other diagonal is half of the first diagonal. Therefore, the second diagonal has a length of 9in.
Knowing this, we can substitute into the formula. We get
