What is the area of the figure?
uysha [10]
I think it'd be 10in. If you cut it into three parts, where the bottom is sectioned off from the other two rectangles, the two rectangles on the side both have an area of 3in, so together they'd be 6in. The rectangle on the bottom has a length of 4 and a width of 1, so it'd be 4in... add those together and get 10in. Hope this helps

Aidan drives to school and back each day. The school is 16 miles from his home. He averages 40 miles per hour on his way to scho
yarga [219]

Answer:

  26 2/3 mph

Step-by-step explanation:

  time = distance/speed

  speed = distance/time

Use the first of these relations to find Aidan's time getting to school:

  time = 16 mi/(40 mi/h) = 16/40 h = 0.4 h

Then the time Aidan takes to get home is 0.6 hours, and his average speed for that trip home is ...

  speed = 16 mi/(0.6 h) = 26 2/3 mi/h
