the width of a rectangle is 10 meter and its area is 150 square meter . if length of the rectangle is increased then its new area is 4 / 3 times of the original area . what is the new perimeter of the rectangle ?
let length of new rectangle be x m then x × 10 = 150 × 4 / 3 = 200 or , x = 20 m hence new perimeter = 2 ( 10 + 20 ) = 60 m answer : d
rectangle_perimeter(divide(divide(multiply(150, 4), 3), 10), 10)
