For periods A and D, formulas and variables

For the quiz you will need to know how to:

take a formula, for example A = lw and substitute in values given to you to find area. For example if you are given:
l = 9 cm
w = 5 cm

You can plug those into the formula A = lw = (9 cm)(5 cm) = 45 square centimeters

You may also encounter a formula dealing with distance, speed, and time. You will need to know to substitute the given values into the formula and solve the formula as shown above in the area formula.
