Question

Which one of them has the greatest perimeter? (Considering Perimeter of one square grid is 1 cm)

• A.
• B.
• C.
• D.

Answer 1

The correct option is D

Given
1 square = 1 ${cm}^2$

Figure 1:

Number of sides = 18
Perimeter = 18 cm

Figure 2:

Number of sides = 16
Perimeter = 16 cm

Figure 3:

Number of sides = 14
Perimeter = 14 cm

Figure 4:

Number of sides = 20
Perimeter = 20 cm

$\therefore$ Figure 4 has the greatest perimeter.
