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) = 15cm²
area of green part = area of rectangle 2
* 3 + area of triangle (1/2) * 1 * 2
= 6 + 1 + 1
= 8 cm²
area of yellow part = 15 - 8 = 7 cm²
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 than it would be 8/5 cm & 7/5 cm from other line
