Question 1119134
<br>
(a) 10x12 rectangle plus two right triangles each with legs 9 and 12; area is 10*12=120 plus 2(9*12)/2 = 108; total area 228.<br>
(b) height times average of the bases: 12(10+28)/2 = 12*19 = 228.<br>
(c) WOW! What a surprise!  The answers are the same!!!<br>
(d) tent: 10+28+15+15 = 68; sleeping bag: 2(6.7+2.3) = 18.<br>
(e) 6.7*2.3 = 15.41 sq ft.<br>
(f) 228/15.41 = 14.8; so 14 sleeping bags if they can't overlap a bit.
