Using our calculator can save you time and prevent calculation errors. Simply enter the known length/width and dioganal of the rectangle, and our calculator will use the rectangle side formula to find the length of the unknown side. Use our free online calculator to find the length of the unknown side of a rectangle. The formula for the perimeter of a rectangle relates. The width is two feet less than the length, so we let (L-2) width. Since the width is defined in terms of the length, we let (L) length. Therefore, the width of the rectangle is 33.54 units. the length and width of a rectangle: Step 3. We can use the rectangle side formula to solve for the width of the rectangle: Example 2įind the width of a rectangle with a length of 10 units and an dioganal of 35 units. Therefore, the length of the rectangle is 14.14 units. We can use the rectangle side formula to solve for the length of the rectangle: Keep reading if you want to understand what a rectangle is, you're interested in the rectangle definition, formulas, and properties of a rectangle. Example 1įind the length of a rectangle with a width of 5 units and an dioganal of 15 units. All you have to do is input the length and width (or diagonal) and allow this rectangle calc to find the values of P (perimeter) and A (area). Here are some examples of how to use the formula to find the length of a side of a rectangle. Using the formula above, you can rearrange it to solve for any of the sides. Where d is the dioganal of the rectangle, b is the length of the rectangle, and a is the width of the rectangle. The formula to calculate the length of a side of a rectangle is: Simply input the known side and dioganals lengths of the rectangle, and our calculator will find the length of the unknown side. The rectangle side can be found by the diagonal and other side, according to the Pythagorean theorem, since the diagonal divides the rectangle into two equal right triangles. If you need to find the length of one of the sides of a rectangle, our free online rectangle side calculator can help. Length 4.5 m and Breadth 1.6 m Area of the rectangle Length x Breadth Hence, Area of the rectangle (4.5 x 1.6) m 2 7.
