Help Me With This Please<br> #Geometry

First, you find the area of one triangle.

Area of Triangle= 1/2 base x height

here we plug in

(1/2)5 x 7
2.5 x 7
17.5

So 17.5 is the area of one triangle, you have 4
so we multiply 17.5 x 4= 70

Now we need to find the area of the base which is a square so the area = length x width or side x side

plug in 5 x 5= 25

so we add everything up 70+25= 95

Answer is choice c 95 ft sq.

Answer:

y=10.1(x)

x=\frac{y}{10.1}

Step-by-step explanation:

It is said in the problem that y would represent how much money she earns and x represents the number hours she works.

so it also said that the amount of Jessa earns is proportional to the amount of time she works .

finding y will be easy dividing 252.50 by 25 will give you 10.1

so how did we get that equation

y will represent the amount and x will represent the hours
