How do you find the length and width of a rectangle when given the perimeter?
To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.
What is the length of the rectangle if its perimeter is 400 meter and its sides of the ratio is 7 3?
Answer Expert Verified. The Length of the Rectangle is 140 m and Breadth is 60 m.
What is the maximum area of a rectangle with a perimeter of 400?
The highest point, the vertex of the parabola, is (20,400) . When w=20 , we also know that l=20 (which forms a square) and the maximum area of the rectangle (square) is 400 ft2 .
How do you find the length and width of a rectangle if you only have the area?
A = L * W, where A is the area, L is the length, W is the width or breadth. NOTE: When multiplying the length by the width, always ensure you work in the same unit of length.
How do I find the length of a rectangle?
To calculate the length and width of a rectangle first, calculate the value of width ‘w’ by using the area of rectangle formula that is, ‘w = A/l’.
What is the length of a rectangle with an area of 108 sq cm and the side are in the ration 4 3?
Therefore the perimeter of the rectangle is 42 cm. Hope this helps !!!
How is the perimeter of a rectangle determined?
A rectangle is defined by the dimensions length and width. It has four sides, and also the opposite sides of a rectangle have the same length. You are given the perimeter of a rectangle. The perimeter, as you know, is the total distance along the outside of the rectangle. The formula used to calculate perimeter is:
How do you find the width of a rectangle?
Set up the formula for the diagonal of a rectangle. The formula is D=w2+l2{displaystyle D={sqrt {w^{2}+l^{2}}}}, where D{displaystyle D} equals the length of the rectangle’s diagonal, l{displaystyle l} equals the length of the rectangle, and w{displaystyle w} equals the width of the rectangle.
How do you find missing dimensions in a rectangle?
There are numerous ways to find a missing dimension of a rectangle, and the method you use will depend on what information you already have. As long as you know the area or perimeter, as well as the length of one side of the rectangle (or the relationship between the length and width), you can find a missing dimension.
How to determine the length of a square?
If you know the area, you can immediately determine the length of each side, because it’s the square root of the area. Example: What are the lengths of the sides of a square with an area of 20 m2? The length of each side of the square is the square root of 20, which is 4.47 meters.
