To find the perimeter of the rectangle you add up all the sides. There are two lengths and widths for every rectangle, so you know the length is 40 meters x 2 = 80 meters. Perimeter is the total length of all the sides so you just minus 120 from the two lengths which is 80. So the width is 40, divide 2 (2 widths) = 20 meters. Width = 20 meters OR if they're asking for widthS then it'll be 40 meters, but they're not.
you multiply the length by two then you multiply the width by two and then add the two answers 2l+2w
A rectangle has two pairs of equal sides. So to calculate the perimeter, add two known sides and multiply by two. 45 + 10 = 55 55 x 2 = 110 Perimeter - 110 metres.
You multiply the length by 2 (because there are two sides of the rectangle that have that measure). You then subtract that number from the perimeter. The number you will be left with is twice the width, so you divide that by two and you get the width of the rectangle.
32 meters The perimeter (distance around the outside) = length + width + length + width P = 2L + 2W 2 (9) + 2 (7) = 18 + 14 = 32 also: P = 2 (L + W) 2(9 + 7) = 32
The area is the length times the width. The perimeter is two times the length plus two times the width.
The dimensions of a rectangle are the length and the width. With these two measurements , the area of the rectangle can be calculated : Area = length x width. The perimeter can also be found : Perimeter = (2 x length) + (2 x width).
A rectangle has two dimensions - length and width. Only if both dimensions are doubled, then the perimeter will be doubled.
Select any two whole numbers that sum to half of 26 = 13.
The perimeter of a rectangle is calculated by adding the lengths of all its sides. In this case, the rectangle has two sides of length 20m and two sides of length 15m. Therefore, the perimeter would be 2(20m) + 2(15m) = 40m + 30m = 70m.
You can find the perimeter of a rectangle if you know its area and the length of one side. Divide the area by the length of the known side and the quotient will be the length of a side perpendicular to the known side, and then multiply the sum of the two sides by two to find the perimeter.
Add up (two lengths) plus (two widths) and you have the perimeter.
