What is the area of adjoining figure?

• 25 sq. units

• 20 sq. units

• 21 sq. units

• 23 sq. units

Answer explanation

Option 4 is correct as the total number of squares covered by the figure is 23. Hence area of figure is 23 sq. units.

What is the area of adjoining figure?

• 9 sq. units

• 15 sq. units

• 14 sq. units

• 12 sq. units

Answer explanation

Option 2 is correct. Number of squares fully covered = 12, Number of half squares covered = 6 6 half squares = 3 full squares Number of less than half covered squares = 4 Hence area covered by figure = number of squares fully covered + number of half squares covered x 1/2 = 12 + 3 = 15 sq. units

What is the area of adjoining figure?

• 16 sq. units

• 18 sq. units

• 15 sq. units

• 17 sq. units

Answer explanation

Option 1 is correct. Number of full squares covered = 13 number of more than half squares covered = 3 Number of less than half squares covered = 2 Hence area covered by figure = number of full squares + number of more than half squares = 13 + 3 = 16 sq. units

If the area of each square is 1 sq. cm then what is the area of the given figure?

• 20 sq. cm

• 27 sq. cm

• 25 sq. cm

• 22 sq. cm

Answer explanation

Option 3 is correct as the figure is made up of 25 squares and area of each square is 1 sq. cm. Hence area of given figure is 25 sq. cm

What is the area of adjoining figure?

• 30 sq. units

• 32 sq. units

• 36 sq. units

• 31 sq. units

Answer explanation

Option 4 is correct. Number of full squares covered = 26 Number of more than half squares covered = 4 Number of half squares = 2 = 1 full square Number of less than half squares covered = 6 Hence area covered by figure = number of full squares + number of more than half squares + 1/2 x number of half squares = 26 + 4 + 1/2 x 2 = 31 sq. units
