Area of a triangle = 1/2 * (base * height)
Base = 9.9 cm
Height = 4.9 cm
So, Area of Δ = 1 / 2 * (9.9 * 4.9)
Area of Δ = 1 / 2 * (48.51)
Area of Δ = 48.51 / 2
Area of Δ = 24.3 cm²

Perimeter = total distance round the Δ
Perimeter = a + b + c
Perimeter = 5.26 + 9.37 + 9.9
Perimeter = 24.53 cm

The type of triangle here is Scalene because all the sides are not equal. Therefore, it is a Scalene triangle.
