Question

the length of breadth of rectangle are in the ratio 3:2 of the area of the rectangle is 726m sq .find its perimeter

Answer 1

Answer: Perimeter of a rectangle is 110cm

Step 1- Length and Breadth are given in ratio = 3:2

            So, Let the length = 3x

            And the breadth = 2x

Formula - area of rectangle = length * breadth

               Area of rectangle = 726 cm square (Given)

              length * breadth = 3x * 2x = 6x square

               6x square = 726

              X square = 726/6  =  x square = 121

              X = √121

               X = 11

Step 2 - Now we put the value of X in length and breadth

              Length = 3X = 3 * 11 = 33 cm

              Breath = 2X = 2 * 11 = 22 cm

Step 3 - Formula - Perimeter of rectangle = 2 (length + breadth)

              Perimeter of Rectangle = 2 (33 + 22) = 2 * 55

              Perimeter of rectangle = 110 cm
