What Is the perimeter if a rectangle if the area is 45cm2?
Well, well, well, aren't we getting fancy with our math questions? If the area of a rectangle is 45cm2, and you want to find the perimeter, you need more information. The length and width are required to calculate the perimeter, so without those dimensions, I'm afraid I can't give you a straight answer.
What is the area of 20 cm2 and the perimeter of 18 cm?
To find the area of a rectangle, you multiply its length by its width. Given the area of 20 cm², we need to find two numbers that multiply to 20. The possible dimensions are 4 cm by 5 cm or 2 cm by 10 cm. To find the perimeter of a rectangle, you add up all its sides. With a perimeter of 18 cm, the possible dimensions are 4 cm by 5 cm, as 4 + 5 + 4 + 5 = 18 cm.
