Question

If each small square covers an area of 1 sq. cm, the difference between the area of the smallest and the biggest stamp is _____ sq. cm.

Answer 1

Number of squares enclosed by stamp A = 18
Area enclosed by stamp A = 18 x 1
= 18 sq. units
Number of squares enclosed by stamp B = 8
Area enclosed by stamp B = 8 x 1
= 8 sq. units
Number of squares enclosed by stamp C = 6
Area enclosed by stamp C = 6 x 1
= 6 sq. units
Number of squares enclosed by stamp D = 12
Area enclosed by stamp D = 12 x 1
= 12 sq. units
Number of squares enclosed by stamp E = 4
Area enclosed by stamp E = 4 x 1
= 4 sq. units
Number of squares enclosed by stamp F = 12
Area enclosed by stamp F = 12 x 1
= 12 sq. units
So, we can see that stamp A covers largest area, whereas stamp E covers least area.
The difference between the area of the smallest and the biggest stamp = 18 - 4
= 14 sq. units
