Possible Answers:

\(\displaystyle 17\textup{ square units}\)

\(\displaystyle 19\textup{ square units}\)

\(\displaystyle 18\textup{ square units}\)

\(\displaystyle 16\textup{ square units}\)

Correct answer:

\(\displaystyle 18\textup{ square units}\)

Explanation:

Area is the amount of space inside the boarder of a two dimensional shape. This shape is made up of unit squares. We can count the number of squares within the shape to find the area. 

There are \(\displaystyle 18\) squares within the shape, so the area is \(\displaystyle 18\textup{ square units}\)

Example Question #1 : Measurement And Data

Megan is working on a science experiment. She needs \(\displaystyle 4\) times the amount of water that she has shown on the scale below. How much water does she need?  

11 g

Possible Answers:

\(\displaystyle 52g\)

\(\displaystyle 44g\)

\(\displaystyle 40g\)

\(\displaystyle 48g\)

Correct answer:

\(\displaystyle 44g\)

Explanation:

Megan has \(\displaystyle 11g\) of water. If she needs \(\displaystyle 4\) times that amount, we can multiply to find our answer. 

\(\displaystyle \frac{\begin{array}[b]{r}11\\ \times\ 4\end{array}}{ \ \ \ \ \ \space 44g}\)

Possible Answers:

\(\displaystyle 40in\)

\(\displaystyle 37in\)

\(\displaystyle 39in\)

\(\displaystyle 38in\)

Correct answer:

\(\displaystyle 38in\)

Explanation:

The formula for perimeter of a rectangle is \(\displaystyle P=2(l + w)\)

To solve for the perimeter we can plug our known values into the equation. 

\(\displaystyle P=2(11+8)\)

\(\displaystyle P=2(19)\)

\(\displaystyle P=38\)
