Question

The sum of the interior angles of a polygon are 1440. How many sides does the polygon have? Solve.

Answer 1

let the no of sides of polygon be n .
So according the question
( 2n -4) × 90 = 1440
180n -360= 1440
180n = 1800
n=10

Answer 2

⚫ IF ALL ANGLES TOGETHER ARE 1440 CM

→ consider it a decagon = 10 sides

10x = 1440
X = 1440/10
= 144 cm

so the polygon is 10 sided ..
