How many square meters are needed to make 40 pieces of wooden padded equilateral triangles with sides of 30 cm and heights of 26 cm?

Correct answer:

S =  1.56 m2

Step-by-step explanation:

n=40 a=30 cm m=30:100  m=0.3 m h=26 cm m=26:100  m=0.26 m  S1=2a h=20.3 0.26=100039=0.039 m2  S=n S1=40 0.039=1.56 m2
