The perimeter of a rectangle is calculated by adding the lengths of all its sides. In this case, the length is 12m and the width is 3m. Therefore, the perimeter would be 2(12m) + 2(3m) = 24m + 6m = 30m.

If length of a rectangle is 4m and width is 2m what is the perimeter?

Well, darling, if the length of your rectangle is 4m and the width is 2m, then the perimeter is simply calculated by adding up all the sides, which gives you 4m + 4m + 2m + 2m, totaling 12 meters. Voilà, there's your answer!


What is the perimeter of a rectangle 12m 8m?

Well, honey, to find the perimeter of a rectangle, you add up all the sides. So, for your rectangle with sides of 12m and 8m, you simply add 12 + 12 + 8 + 8 to get a perimeter of 40 meters. Voila!


a rectangle measures 3m by 12m, what is the area?

Oh, dude, it's like super simple math. The area of a rectangle is just the length times the width, so for this one, it's 3m x 12m which equals 36 square meters. Like, no big deal, just basic math stuff.

The area of a rectangle is 72 square meters and its length is twice its width. What is the length and width of the rectangle?

The length of the rectangle in question is 12 meters, and the width of the rectangle is 6 meters.We solve this by knowing that the area of a rectangle is equal to the length (l) times the width (w). That formula looks like this:Arectangle = l x wWe are told that the length is twice the width. Here's that idea in the form of an equation:l = 2wSince the length is twice the width, we can substitute the 2w for the l in the first equation. It looks like this:Arectangle = 2w x wNow we add the fact that the area was given as 72 meters2. and put it all together. It looks like this:72 meters2 = 2w x w72 meters2 = 2w236 meters2 = w2sqrt 36 meters2 = w6 meters = wWe have our width as 6 meters. The length is twice that, or 6 meters x 2 = 12 meters. There are our length and width. Let's check our work.Area = length (12 meters) times width (6 meters) = 12m x 6m = 72 m2Our work checks.

What is the perimeter of a rectangle that has a length 12 m and width 3 m?

The perimeter of a rectangle is calculated by adding all four sides together. In this case, the length is 12m and the width is 3m. The formula for the perimeter of a rectangle is P = 2(length) + 2(width). Therefore, the perimeter of this rectangle would be P = 2(12m) + 2(3m) = 24m + 6m = 30 meters.

What is the perimeter of a rectangle 3m x 1.5m?

The perimeter of a rectangle is calculated by adding up the lengths of all its sides. In this case, the rectangle has two sides of 3m each and two sides of 1.5m each. Therefore, the perimeter would be 3m + 3m + 1.5m + 1.5m = 9m.


What is the perimeter of a rectangle measuring 4.5m by 1.5m?

The perimeter of a rectangle is the distance all the way round it.That's lenght (4.5m) + a breadth (1.5m) + another length (4.5m) + another breadth (1.5m) = 12m.Algebraically, the perimeter is 2(l + b), where l is the length and b is the breadth, = 2 x (4.5m + 1.5m) = 2 x 6m = 12m.
