(a) a square
(b) an equilateral triangle
(c) a regular pentagon
(d) a regular hexagon
(e) a regular decagon
​

Answer 1

Answer:

15, 20, 12, 10, 6

Step-by-step explanation:

(a) a square = 4 sides = 60/4 = 15cm

(b) an equilateral triangle = 3 sides = 60/3 = 20cm

(c) a regular pentagon = 5 sides = 60/5 = 12cm

(d) a regular hexagon = 6 sides = 60/6 = 10cm

(e) a regular decagon = 10 sides = 60/10 = 6cm
