How many m2 of fabric is needed to make a tent of a regular 3-sided prism if it is necessary to count on a 2% reserve of fabric? Dimensions - 2m 1.6m and height 1.4m

Correct answer:

S =  8.4716 m2

Step-by-step explanation:

a=2 m b=1.6 m h=1.4 m  p=1+1002=1001 100+1002=100100+1002=100100+2=100102=5051=1.02  S1=a h/2=2 1.4/2=57=1.4 m2 s=h2+(a/2)2=1.42+(2/2)21.7205 m  S2=b s=1.6 1.72052.7527 m2  S=p (2 S1+2 S2)=1.02 (2 1.4+2 2.7527)=8.4716 m2
