Formulas of area and perimeter
WebArea of sector = θ 360 ∘ × π r 2. If is measured in radians, then “the area of a sector of a circle formula” is given by. Area of sector = 1 2 × θ × r 2. Perimeter of sector = 2 r + θ 360 × 2 π r. WebThe area of the square, as calculated above, is 25 square units. The area of the triangle can be determined as A = ½bh, where b is the base and h is the height: ½ (5) (8) = 20 The total area is therefore: 25 + 20 = 45 square units Area can also be determined using the concept of unit squares.
