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.

Result

a =  54.083 cm
b =  5670 cm2

Solution:

a=(60/2)2+(90/2)2=54.083 cma=\sqrt{ (60/2)^{ 2 }+(90/2)^{ 2 } }=54.083 \ \text{cm}
b=2 (60 90/2) 1.05=5670 cm2b=2 \cdot \ (60 \cdot \ 90/2) \cdot \ 1.05=5670 \ \text{cm}^2
