Kite

John a kite, which is diamond shaped. Its diagonals are 60 cm long and 90 cm long. Calculate:

a) the diamond side
b) how much paper John needs to make a kite if he needs paper on both sides and needs 5% of the paper for bending.

Correct result:

a =  54.0833 cm
b =  5670 cm2

Solution:

a=(60/2)2+(90/2)2=54.0833 cm
b=2⋅ (60⋅ 90/2)⋅ 1.05=5670 cm2
