Diamonds puzzle

The puzzle is composed of paper diamonds. One diamond has a tent 3.4 cm long and a corresponding height of 2.5 cm. How much paper in dm squares is needed for 60 diamonds?

Correct answer:

S =  5.1 dm2

Step-by-step explanation:

a=3.4 cm h=2.5 cm n=60  S1=a h=3.4 2.5=172=8.5 cm2 S2=S1 dm2=S1/100  dm2=8.5/100  dm2=0.085 dm2  S=n S2=60 0.085=5110=5110 dm2=5.1 dm2
