Grade: 6-a Lesson: S2-L6 |
Explanation: The best way to understand measurement is by looking at some examples. Take turns and read each example for easy understanding. |
Examples:
Find the length of a rectangle with an area of 34 square inches, given that one of its sides is 7 inches.
Step 1a
|
|
To find the length of a rectangle with an area of 34 square inches, given that one of its sides is 7 inches, you can use the formula for the area of a rectangle: Area = Length × Width In this case, we know that the area is 34 square inches and the width is 7 inches. We can rearrange the formula to solve for the length: \$"Length" = "Area" / "Width"\$ |
|
Explanation: Here, we use the length formula. |
Step 1b
|
|
Substituting the known values: \$"Length" = (34 "square inches") / (7 "inches") \$ Length ≈ 4.857 inches (rounded to three decimal places) Therefore, the length of the rectangle is approximately 4.857 inches. |
|
Explanation: After substituting the known values, the length of the rectangle is approximately 4.857 inches. |
