Question

Let ABCD and EFGH be two quadriaterals such that ABCD ~ EFGH If AB= 15cm, EF =18cm and the permeter of ABCD is 40cm, find the permeter of EFGH.

Answer 1

52

Explanation:

If ABCD ~ EFGH

AND AB = 15 and EF = 18 and ABCD = 40

then

each side of ABCD should be 3cm less then side of EFGH

AB + BC + CD + DA = 40

AB + 3 + BC + 3 + CD +3 + DA + 3= P(EFGH)

40+12 = 52 = P(EFGH)
