the area of a rectangular field is equal to 750 square meters . its perimeter is equal to 110 meters . find the width of this rectangle .
l * w = 750 : area , l is the length and w is the width . 2 l + 2 w = 110 : perimeter l = 55 - w : solve for l ( 55 - w ) * w = 750 : substitute in the area equation w = 25 and l = 30 correct answer e
divide(subtract(divide(110, const_2), sqrt(subtract(multiply(divide(110, const_2), divide(110, const_2)), multiply(const_4, 750)))), const_2)
