Answer:

The area is  522.935 square inches.

Step-by-step explanation:

A trapezoid's area is calculated as follows: h(b1+b2)/2

Plugging numbers in gives 34.3+12.6=46.9

so now all that's left is to multiply 22.3 and 46.9, and divide by 2.

This gives 522.935

Hope this helps!

Explain how multiplying playing with 6 is like multiplying with 3
mote1985 [20]
6 is only the double of 3
3×2=6

Any number that's multiplied by 6 will be the double of any number multiplied by 3, or vice versa, any number multiplied by 3 will be half of any number multiplied by 6. This is because 6 is a multiple of 3.

Take for example:
850×6=5100 ⇔ 850×(3×2)=5100
