3. To just put a tile on the kitchen floor, we must know the perimeter of the of the floor. If the entire floor has to be covered by tiles then we need to know the area.

4.

i. Square seems to have larger area.

ii. Rectangle seems to have larger perimeter.

iii. Area of rectangle is l X b = 8X2 = 16m²

    Area of square is (side)² = 4 X 4 = 16m²

   Perimeter of rectangle is 2(l+b) = 2(8+2) = 20m

   Perimeter of square is 4 X side = 4 X 4 = 16m

iv. Area is equal for both the figures.

v. Perimeter of rectangle is greater than the perimeter of square.

5. Diagram helps us understand what exactly is happening and thus help in writing the equation correctly.
