Answer 1

Answer: The answer to question 1 is 180 in. The answer to question 2 is 54 in. sq. And the answer to question 3 is (2,3)

Step-by-step explanation:

To solve question 1, we need to identify the remaining length of the shape. I've done that in an image below. The next step is to add all of those sides together. It would be 20+20+20+20+20+10+10+60 = 180 inches in length.

To solve question 2, all you need to do is follow the formula A = [h(b) x b] /2

Which may look scary but never fear! Written in understandable words it essentially says, multiply the height by the base then divide by 2.

A = (6 x 18) ÷ 2

A = 108 ÷ 2

A = 54 meters squared

For the last question, I'm not sure what the formula is, but I have a way of doing it that isn't too confusing. Simply add the x values and add the y values, then divide them by 2 to get their halve. Now the new x and y values are your midpoint. (Do not add the x + y values, only the x + x and y + y)

See :

-3 + 7 = 4      4 ÷ 2 = 2

8 + (-2) = 6    6 ÷ 2 = 3

So your new coordinates are (2,3)

I hope this helped you understand :)
