One of the sides of a parallelogram is increasing at a rate of 10cm / s and one of the adjacent ones is decreasing at a rate of 5cm / s, while the angle between these sides is increasing at a rate of 2 ° / s. Determine how and how fast the area of the parallelogram at the instant when such sides measure 2.4 m and 1.5 m respectively and the angle understood is 60 °
