Sketch the following to help answer the question. Kite QRST has a short diagonal of QS and a long diagonal of RT. The diagonals

Natalija [7]

The two diagonals intersects at right-angle for a kite

the long diagonal also bisects the short diagonal so QP = PS = QS/2 = 6/2 = 3

QPR is a right-angle triangle with QR at 5 and QR at 3

RP = sqrt (5^2 - 3^) = 4m

A kite has a height of 36 inches and a width of 30 inches. Explain how to use the area formula for a triangle to find the area o

mote1985 [20]

Height of the kite is = 36 inches.

Width of the kite is = 30 inches

One of the ways to find the area is to draw a vertical line to break the kite into two equal triangles. Mark the base as 36 inches and height as 15 inches .

Now we will use the formula $area=\frac{1}{2}*base*height$ to find the area of each triangle. Then we will add both the areas to find the area of the kite.
