Answer:

I am pretty sure it is 249.86 square feet.

Step-by-step explanation:

Find the area of the rectangle:

15.5*12.4=192.20 (base x height)

Find the area of the triangle:

9.3*12.4=115.32\\115.32/2=57.66 (base x height divided by 2)

Add the 2 areas together:

192.20+57.66=249.86

Jobisdone [24]
Answer:
3c=273
c=91
2c= 212
C= 106
c= 91+ 106= 197
so they will need 197 canoes total

Why:
So first you have to determine a set variable to represent the number of canoes, I chose C. Then you make an equation to represent the number of canoes 273 people will use if they group into 3's, from this I got 3c=273. Solve for C and get 91.
The remainder of the group which is 485-273= 212 will use canoes in groups of 2's. To represent this, 2c=212. Solve for C and get 106. Combine 106 and 91 to get the total number of canoes.
