**Area of sector worksheet :**

Here we are going to see 10 problems based on the concept area of sector.

We are having two formulas to find area of any sector. We can choose one of the formulas given below based on the given information.

Whenever we have the angle formed by the sector and radius of the sector, we use the formula given below.

Area of the sector = (θ/360) x Π r ² square units

Whenever we have the arc length formed by the sector and radius, we use the formula given below.

Area of the sector = (1/2) x l r square units

θ - central angle formed by the sector

L - length of arc

r - radius of the sector

(1) Find the area of sector whose perimeter is 78 cm and central angle is 45°

(2) Find the area of sector whose perimeter is 64 cm and central angle is 60°

(3) Find the area of sector whose perimeter is 92 cm and central angle is 36°

(4) Find the area of sector whose perimeter is 43 cm and radius is 10.5 cm

(5) Find the area of sector whose perimeter is 86 cm and radius is 21 cm

(6) Find the area of sector whose perimeter is 56 cm and radius is 10 cm

(7) Find the area of sector whose perimeter is 64 cm and radius is 14 cm

(8) Find the area of sector whose perimeter is 45 cm and radius is 10 cm

(9) Find the area of sector whose perimeter is 147 cm and radius is 35 cm

(10) Find the area of sector whose length of arc is 21 cm and radius is 66 cm
