You are looking for the sides of a rectangle x,y such that x*y=20, and 2(x+y)=18.

Hint: the problem's solution is in integers. So all you need to try are the factors of 20 to make x*y=20, and verify the perimeter.

2. Correct!

3. Check the figure

Q-------------R----T

......14.........5

What is the length of QT?

4. Correct!

How did you find the answer?

5.

A linear pair of angles means that two angles are adjacent and the total is supplementary (180°). If one is acute (less than 90), so what is the other? (180-(less than 90°).

Feel free to post your answers for checking.
