Susan wants to build a kite with two sticks that measure 12in and 20in.
To determine how much fabric she needs, she has to calculate the surface area of the kite.
To calculate the area of the kite you have to multiply the diagonals p and q and divide the result by 2
[tex]A=\frac{p\cdot q}{2}[/tex]
For p=12in and q=20in
[tex]\begin{gathered} A=\frac{12\cdot20}{2} \\ A=\frac{240}{2} \\ A=120in^2 \end{gathered}[/tex]
She will need 120in² of fabric to cover th
