the longer diagonal is 4 more than the shorter diagonal of a kite. The area is 5 times the shorter diagonal. If the shorter side is 6 cm. Find the longer diagonal and the area.

Correct
15

Explanation:
This problem can be solved by applying the area formula:

Since this question provides the area of the kite and length of one diagonal, plug that information into the equation to solve for the missing diagonal.

Thus the solution is:

60=8×diagonalB2

60×2=8×diagonalB

120=8(diagonalB)

diagonalB=1208=15

Are there any statements?
