the length of a rectangle is a three time of its breadth if the area of the rectangle is 432 CM square then find the perimeter |
|
Answer» Answer: 96 centimeters. Step-by-step explanation: Let the breadth of the RECTANGLE be N. LENGTH = 3n Area of the given rectangle = 432 cm² Area = length x breadth 432=3n x n 432=3 x n x n 432/3=n² n²=144 n=√144 n=12 cm. Breadth = 12 cm Length=3 x 12 = 36 cm Perimeter of a rectangle = 2(l+b) =2(36+12) =2 x 48 =96 cm. |
