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.
