Decomposition of the trapezoid to find the area. You first need to separate the parts of the trapezoid that make a triangles. Ex: separate the outer parts so that you're left with triangle/s and a rectangle/square shape in the middle. Find the area of the triangles and the area of the middle square/rectangle and then add that together.
8. 171 I used this formula A=(a+b)h/2 Which is top length+bottom length times height divided by two.
Trapezoid area:
You need to add the top base and the bottom base together then multiply that by the height.
9. 396. I used the same formula as the last one. which is A=(a+b)h/2.
I hope I could help you :)

Which is closest to the surface area of a cone with dimensions as shown?
A. 113 mm2
B. 75 mm2
C. 66 mm2
D. 207 mm2
Answer:
B
Step-by-step explanation:
A=πr(r+h2+r2)=π·3·(3+42+32)≈75.39822
Answer:
75.39 mm²≈ 75 mm²
Step-by-step explanation:
A=πrl+πr²
l=[tex]\sqrt{r^2+h^2}[/tex]
A=πr(r+[tex]\sqrt{r^2+h^2}[/tex])=π·3·(3+[tex]\sqrt{4^2+3^2}[/tex])≈75.39 mm²
75.39 mm² ≈ 75 m²

Answer plsssssssssssssssssssssssssssssss
Answer:
I would say the answer is C: Find the perimeter of the painting; and
35 inches.
Step-by-step explanation:
Ok, I might be super-duper wrong, but please don't hate me!!!
I think the answer is C. because to know how much money you need, you need to find how much something costs.
It also asks for you to answer the first step, or find the perimeter.
Formula of perimeter = b2 + w2 (base times two plus the width times two).
6 1/4 * 2 = 12.5
11 1/4 * 2 = 22.5
12.5 + 22.5 = 35.
The two answers are C: Find the perimeter of the painting and
35 inches.

On a road trip, Lota drives 55 miles each hour. The table below shows how far she travels each hour.
h hrs of driving 1 2 3 4 5 6
m miles completed 55 110 165 220 275 330
Which equation represents the relationship between h, the number of hours she drives and m the number of miles she completes?
m = h/55
m = 55/h
m = 55h
m + h = 55
Answer:
I believe the answer is M=55/h
Answer:
m = 55h
Step-by-step explanation:
m= 55h or
h*55=m
1*55=55
2*55=110
3*55=165
4*55=220
5*55=275
6*55=330
