The directions for mixing an insect spray say to use 1 1/2 ounces of chemical in each gallon of water. how many ounces of chemical should be mixed with 3 4/5 gallons of water? first, estimate the answer to the application problem. then find the exact answer.

Given that ounces of chemical required for each gallon.

Total amount of chemical required for gallons water will be product if and that is approximately  2*4 = 8 ounces ( means 3+() 3.8 ≈4 and means 1+() 1.5≈2)

Exact amount = 1.5*3.8 = 5.7 ounces.

there are lots of ways.   pick's theorem tells us if the vertices are lattice points the area a is

a = b/2 + i - 1

where b is the number of boundary lattice points and i is the number of interior lattice points.

in the figure i count b=16, i=50 so

a = 8 + 50 - 1 = 57

let's try the shoelace formula.   the area is half the sum of the cross products of the sides.  

a(-2,6)   -2(2)-6(-5) = 26

b(-5,2)   -5(-3) - 2(-2) = 19

c(-2,-3) -2(-3) - (-3)(4) = 18

d(4,-3)   4(3) - (-3)(5) = 27

e(5,3)   5(3) - 3(1) = 12

f(1,3)     1(6) - 3(-2) = 12

a(-2,6)

each of the cross products is twice the area of the triangle with the associated side and one vertex the origin. so the area of abo=26/2=13.

area = (1/2) (26 + 19 +   18 + 27 + 12 + 12) = 57

that checks!
