$\sf \longmapsto S_{ 20} = \dfrac{n}{2} \times 2a + (n - 1)d \\ \\ \sf\longmapsto S_{20}= \dfrac{20}{2} \times 2(2) + (20 - 1)6 \\ \\ \sf\longmapsto S_{20} = 10 \{ 4 + 114 \} \\ \\ \sf \longmapsto \boxed{\bf{S_{20} = 1180}}$

nalin [4]

Answer:

If the perimeter = 300m

let the ratio be in x 

a/q. 

3x + 5x + 7x. = 300m

15x = 300

x = 300/15

x = 20

hence angles are 

60 , 100 and 140
