Aswing set is going to be placed over a region of mulch that is shaped like a trapezoid. the bases of the trapezoid have a length of 12 and 15 feet, and the perpendicular distance between the bases is 8.5 feet. what is the area of the region under the swing set? if necessary, round your answer to the nearest tenth.

Step-by-step explanation:

we know that

The area of a trapezoid is equal to

In this problem we have

----> the height of the trapezoid is the perpendicular distance between the bases

substitute the values

Round to the nearest tenth

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
