The length is 8 m, the width is 2 m less than its length. Find the area of this greenhouse.

First, you need to determine the width of this greenhouse.
Since we know that it is 2 meters less than the length, for this we subtract the difference from the indicated length of the greenhouse, namely 2 meters.
Will be:
8 – 2 = 6 meters.
We find the area of the greenhouse.
To do this, we multiply the length and width of the greenhouse together.
Will be:
8 * 6 = 48 m2
The perimeter of the greenhouse will be equal to twice the sum of the length and width and will be:
2 * (8 + 6) = 2 * 14 = 28 meters.
Answer: The greenhouse area is 48 m2
