Answer:
59.15 in^2
Step-by-step explanation:
Using Heron's formula
semiperimeter , s = 1/2 ( 28.8+18+12) = 29.4
Area = sqrt ( 29.4(29.4-28.8)(29.4-18)(29.4-12) ) = 59.15 in^2

Answer:
The whole tank cost $55.13
Step-by-step explanation:
All you have to do is multiply the fraction and cost, to ge thte total cost
15 3/4 also equals 15.75 (it will be easier to multiply two fractions)
now each gall of the 15.75 costs 3.50 so we multiply the number of gallons by the cost
15.75 x 3.50 = 55.125
but now we must round since there isnt .125 cents
so
55.13 is the cost
