The Scout Tent has a rectangular wooden underlay with dimensions of 220 cm and 150 cm. How much canvas is needed for a 170 cm high pyramid roof?

Correct answer:

x =  7.1251 m2

Step-by-step explanation:

a=220 cm m=220/100  m=2.2 m b=150 cm m=150/100  m=1.5 m h=170 cm m=170/100  m=1.7 m  h1=h2+(b/2)2=1.72+(1.5/2)21.8581 m h2=h2+(a/2)2=1.72+(2.2/2)22.0248 m  S1=a h1/2=2.2 1.8581/22.0439 m2 S2=b h2/2=1.5 2.0248/21.5186 m2  x=2 (S1+S2)=2 (2.0439+1.5186)=7.1251 m2
