Question

Which has larger perimeter : a square of side 3 cm, decagon of side 2 cm, pentagon of side 5 cm and equilateral triangle of side 2 cm

Answer 1

Step-by-step explanation:

sides of square = 4

length of side = 3cm

perimeter = 4 x 3

= 12cm

sides of decagon = 10

length of side = 2cm

= perimeter = 10 x 2

= 20cm

sides of Pentagon = 5

length of side = 5cm

= perimeter = 5 x 5

= 25cm

sides of equilateral triangle= 3

length of side = 2cm

= perimeter = 3 x 2

= 6cm

so the Pentagon of side 5cm has the longest perimeter so it the perimeter

Answer 2

$2 {2 {5 {8}^{?} }^{2} }^{2}$
