Area of sector
= 2 × radius + length of the arc = 25
Length of the arc = 25 – 2 × radius = 25 – 14 = 11 cm
Let us check the ratio between the length of the arc and its area
The length of the arc: Area of the sector
11 : area of the sector = 2:7
Area of two sectors =7 × 11
Area of the. sector = \(\frac{7\times11}{2}\) = 38.5 cm2
