Hi there!
The formula for the area of a kite is A = 1/2(d1 x d2). Using this formula, all we need to do to find the area is to plug in each diagonal length, then solve the equation.
WORK:
A = 1/2(15 x 16)
A = 1/2(240)
A = 120cm^2
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
