Question

find the perimeter of the given figure​

Answer 1

Perimeter of the figure is 45 cm.

• To find the perimeter of the figure , we see that the figure consists of two sectors with same radius.
• The angle made by the sector is 90°.
• Perimeter of a sector (in cm) =  $\frac{2 \pi r}{4}$ +2r
• As the angle made by the arc is 90°, it is one-fourth of the circle.

Perimeter of a sector  = $\frac{2 \pi (6.3)}{4}$ +2(6.3)

Perimeter of a sector  = 22.5 cm

• Now the same sector is placed below.
• Therefore, the perimeter of the figure is 2 times of the above calculated sector.
• Perimeter = 2 × 22.5 cm

Perimeter = 45 cm
