We have, Length = 4.5 m and Breadth = 1.6 m Maximum area of a rectangle whose perimeter is $100$. Its perimeter is 400m. . Both lengths of the rectangle are the same, and both widths are the same. Find the area, in square metres, of a rectangle whose length = 4.5 m and breadth = 1.6 m. Solution . WebTo 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'. Both lengths of the rectangle are the same, and both widths are the same. Let us understand it using an example. Just Now Web Now, let the width be w. Since, the length is 4cm greater than the width, the length will be w+4 cm. Now insert the above equation into the equation for the area (A): The area equation is given as A = ab. Just plug the area and length of the rectangle into the formula and solve for the width. The formulas for the perimeter P and the area A of the rectangle are used to write equations as follows: P = 2 * L + 2 * W. A = L * W. To get this answer, apply the formula diagonal = (P - 8 A). W = P / 2 - L Any combinations will yield a perimeter of 24. Know the perimeter of the rectangle. A rectangle is an example of a quadrilateral. So any combination of numbers that add up to 12 will be our dimensions. For example, if the width of a rectangle is 3 cm, and the length is 4 cm, your formula will look like this: 3 2 + 4 2 = c 2 {\displaystyle 3^ {2}+4^ {2}=c^ {2}} . What's the diagonal of a rectangle formula? A = L * (P / 2 - L) References. The formula for finding the area of a rectangle is given by Area of a rectangle = Length x Breadth.
