The rectangle must have sides with lengths of 20, 20, 10, and 10.
20+20+10+10 = 60 (perimeter)
20*10 = 200 (area)

To find the perimeter of a rectangle you must calculate the lengths of each of the sides and add them all together.
The perimeter of a rectangle is calculated by adding together the lengths of all its sides. In this case, the rectangle has two sides of length 10cm and two sides of length 3cm. Therefore, the perimeter is calculated as 10cm + 10cm + 3cm + 3cm = 26cm.
Yes. The perimeter is a measure of the combined length of all the sides. If you double the lengths of the sides then naturally this will also necessarilychange the perimeter (it will double the perimeter).
Perimeter of the rectangle 24+18+24+18 = 84DC
Add the lengths of all four sides.
