Question

find the following measurements.
parallelogram: base = 10 units height = 4 units
what are the length and width of the rectangle?
rectangle: length = units width = ? units

Explanation:

For the Parallelogram Area (though the question about rectangle is here, first let's recall parallelogram and rectangle relation)

But the rectangle part: Looking at the grid, and the parallelogram has base 10 and height 4. The rectangle (when we transform parallelogram to rectangle by cutting and pasting the triangle) should have length equal to the base of the parallelogram and width equal to the height of the parallelogram.

For the Rectangle:

Step1: Determine length

The parallelogram's base is 10 units, so the rectangle's length (since when we form a rectangle from a parallelogram, the length corresponds to the base of the parallelogram) is 10 units.

Step2: Determine width

The parallelogram's height is 4 units, so the rectangle's width (corresponding to the height of the parallelogram) is 4 units.

Answer:

Rectangle: length = $\boldsymbol{10}$ units, width = $\boldsymbol{4}$ units
