A piece of wire is 60 cm long. What will be the length of each side if the wire is used to for
(i) a square, (ii) an equilateral triangle, (iii) a regular pentagon, (iv) a regular hexag​

Answer 1

Answer:

(I)-15 cm ,(ii)-20cm,(III)-12cm,(iv)-10cm

Step-by-step explanation:

(I) length of wire = 60 cm

let each side of square be a then it's perimeter will be 4a

4a=60

a=15cm

each side of square will be 15 cm

(ii) let each side be a of equilateral∆ because we know that all the sides of an equilateral ∆ are equal. hence,

3a=60

a =20 cm

each side of triangle will be 20cm

(III) let is side of Pentagon be a then,

5a= 60

a=12cm each side of regular Pentagon is 12 cm

(iv) let each side of a regular hexagon be a then,

6a =60

a=10 cm

hence each side of regular hexagon is 10 cm
