The width of the rectangle is 5 m; its length is 2 times greater. What is the perimeter and area.

First, let’s calculate the length of the rectangle, for this we multiply the width by 2 times:
1) 5 * 2 = 10 meters.
The perimeter of a rectangle is the sum of all its sides, so we can calculate it:
2) 5 + 10 + 5 + 10 = 30 meters.
It remains to calculate the area, for this we multiply the length by the width:
3) 10 * 5 = 50 square meters.
Answer: the perimeter is 30 meters, the area is 50 square meters.
