Area of triangle = 1/2 bh
60 = 1/2 (15) h
8 = h
Quadrilateral area = h x (b1 + b2)/2 = 8 x (15+9)/2 = 96 sq units
96 -60 = triangle BAD area = 36 sq units
Answer:
Negative infinity to infinity, 3 to infinity.
Well, for his you would have to find the unit rate.
The easiest way to do this would first be converting 3/5 into a fraction (0.6)
next, divide that by 4 to get the weight of 1.
0.6/4 (the same as 0.6 x 0.25 or 6/10 x 1/4 if you are doing it without a calculator)
each bread weighs 3/20 (or 0.15) pounds.
