What is the area of a rectangle with side lengths of 5 cm and 8 cm?
40 square cm
26 square cm
3 square cm
13 square cm
Area = length x width
Area = 5 cm x 8 cm
Area = 40 square cm
So, the answer is 40 square cm.
If the side of a square is 7 m, then find its area.
49 square meter
48 square meter
45 square meter
42 square meter
Area = side x side
In this case, the side of the square is 7 m. Substituting into the formula above, we get:
Area = 7 m x 7 m
Area = 49 square meters
Therefore, the area of the square is 49 square meters.
So, the answer is 49 square meter.

A shipping box is 10 1/2 in wide, 16 1/2 in long, and 14 1/2 in high. What is the volume of the box in cubic inches?
Volume = length x width x height
Substituting the given values, we get:
Volume = 10.5 in x 16.5 in x 14.5 in
Volume = 2548.125 cubic inches
Therefore, the volume of the shipping box is 2548.125 cubic inches.

Ava is trying to save at least $200 from her summer job to buy new clothes for the coming school year. She has $75 saved. Which inequality below can be used to find x, the amount of money she still needs to save in order to reach her goal of at least $200?
x + 75 ≥ 200
75 + x ≤ 200
x + 75 < 200
75 + 200 ≥ x
In order to find the inequality that represents this situation, we can use the following:
x + 75 ≥ 200
This inequality says that the sum of the money she still needs to save (x) and the money she has already saved ($75) is greater than or equal to her goal of saving at least $200.
So, the answer is: x + 75 ≥ 200.
