A gardener wants to cover a parallelogram-shaped piece of land with colorful flowers. To find the area of the garden, the gardener composes a rectangle. What is the base of the rectangle in meters?

10 m Height
12 m length

The area of a parallelogram is calculated by multiplying the base by the height. Since the gardener has composed a rectangle to find the area of the parallelogram, the base of the rectangle would be the same as the base of the parallelogram.

Therefore, the base of the rectangle (and the parallelogram) is 12 meters.
