What is the area? Can you please help me

31.5

Step-by-step explanation:

We must solve this in sections and the rectangle is the easiest so I solved it first

7×3=21

Now we must solve for the triangles

1/2b×h

I found base by dividing 7 in half

1/2(3.5×3)

1/2(10.5)

5.25

We solved for one of the triangles. Since there's 2, we multiply the answer by 2

5.25×2=10.5

Now we add the sections

21+10.5=31.5

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
