Find the area of this trapezoid. be sure to include the correct unit in your answer.

the area of this trapezoid= 81 square inches

Step-by-step explanation:

To find area of trapezoid , we use formula

Where a,b are the base of the trapezoid

h is the height of the trapezoid

Here a= 3 in

b = 15 in

h = 9 in

Plug in all the values in the formula

Area = 9 * 9 = 81

the area of this trapezoid= 81 square inches

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
