Me . also could you tell me how to do it for future

15200cm^2

Step-by-step explanation:

we can separate this into 2 equivalent triangles , 2 equivalent rectangles, and 1 extra rectangle.

the area of a triangle is 1/2b*h so 40*60*1/2=1200

we have 2 of these triangles so the area of the triangles in total is 2400.

next, the 2 equivalent rectangles. the area of a rectangle is b*h is 80*50= 4000

we have 2 so the area of these rectangles in total is 8000.

lastly we have one more rectangle 60*80=4800.

then we add all these up 2400+8000+4800= 15200

add unit

15200cm^2

and we're done

15 + 2.05 x = 2.35 x

Step-by-step explanation:

Let x be the number of gallons you would have to buy for the two places to be the same.

At the club, there is a monthly fee of $15 that is charged once in a month. They also charge $2.05 per gallon, which is charged every gallon of gas you buy.

We can write an expression: 15 + 2.05 x

At the gas station, they charge $2.35 per gallon with no other fees.

We can also write an expression: 2.35 x

For the prices to be the same, we have 15 + 2.05 x = 2.35 x

If we were to solve, then we have:

(2.35 - 2.05) x = 15

x = 15 / 0.3 = 50 gallons
