Answer 1

Answer:

Let section (1) is opposite of (3) that is along its length

Let section (1) is opposite of (3) that is along its lengthand section (2) is opposite of (4) that is along its breadth

Both opposite section have same area

Area of section (1) & (3) = 28*4 = 112cm²

Area of section (2) & (4) = 24*4 = 96cm²
