Question

Each side of a regular polygon is 3.5 cm in length The
bertmeter of the polygon is 21 cm. How many sides doen
the polygon have?​

Answer 1

Answer:

6

Step-by-step explanation:

$side \: of \: polygon \: = 3.5 \: cm \\ perimeter \: = 21 \: cm\\ let \: no. \: of \: sides \: = n$

FORMULA :

perimeter = no. of sides x length of side

$perimeter \: = 21 \\ n \times 3.5 = 21 \\ n = \frac{21}{3.5} \\ n = 6$

no. of sides of polygon = 6

Answer 2

Answer:

6

Step-by-step explanation:

side \: of \: polygon \:  = 3.5 \: cm  \\ perimeter \:  = 21 \: cm\\ let \: no. \: of \: sides \:  = n \\  

FORMULA :

perimeter = no. of sides x length of side

perimeter \:  = 21 \\ n \times 3.5 = 21 \\ n =  \frac{21}{3.5}  \\ n = 6

no. of sides of polygon = 6
