Answer: B. area = 6

Step-by-step explanation:

You need to divide the miles by the hours to et the Average speed.
M divided by h = s
Because to get the mph (miles per hour) you multiply the average speed to the hours.
S•h=mph

Answer:

126 square units

Step-by-step explanation:

Area of section 1 is 8 square units which is triangle and,

Area of triangle is = $\frac{1}{2}\times b\times h$

b= 2 units and height =8 units

So,

Area of section 1 = $\frac{1}{2}\times 2\times 8=8 \quad\text{ square units}$

Same Area is of section 2 which is also a triangle and has same base and height.

So,

Area of Section 2 = $\frac{1}{2}\times 2\times 8=8 \quad\text{ square units}$

Now the Area of section 3 which is square with side of 10 units

So,

Area of section 3 = $a^{2} =10\times10=100\quad \text{square units}$

Total Area of Trapezoid = $8+8+100=126 \quad \text{square units}$
