Answer» Given : a rectangle divided into two parts. To find : DRAW a straight line to divide the rectangle into two other parts of the same area. Solution: Area of rectangle = 3 * (2 + 3) = 15 cm² Area of green PART = Area of rectangle 2 * 3 + area of triangle (1/2) *2 * 1 + area of triangle (1/2) * 1 * 2 = 6 + 1 + 1 = 8 cm² Area of YELLOW part = 15 - 8 = 7 cm Width of Green rectangle = 8 /3 cm Width of yellow rectangle = 7 / 3 cm a line at a DISTANCE of 8/3 cm from green area side can DRAWN to divide into two rectangle one equal to area of green part & another equal to area of yellow part if line is drawn other way then it would be 8/5 cm & 7/5 cm from other line Learn more: prove that diagonal of a rectangle divide it into two triangle ...
