Length of the rectangle = 15 feet Breadth of the rectangle = 30 feet. Explanation: Let the breadth of the rectangle = x So, the length of the rectangle = 2 × x The perimeter given = 90 feet As per the formula for perimeter of a rectangle Perimeter = 2 × (length + breadth ) 90 = 2 × ( x + 2 x ) 90 = 2 × ( 3 x ) 90 = 6 x x = 90 6 x = 15 So the length of the rectangle = 15 feet, breadth of the rectangle = 30 feet.
