Answer:
A = 344 ft^2
Step-by-step explanation:
Area of a triangle is given by:
A = 1/2(b×h)
In this case, the kite has 4 triangles, but there are two pairs of identical triangles, meaning that we can disregard the 1/2 since 2 x 1/2 is equal to 1.
Thus:
A = 8 ft × 40ft = 320 ft^2
A = 3 ft × 8ft = 24 ft^2
A = 320 ft^2 + 24 ft^2
A = 344 ft^2
