Question

Dacă aș micșora cu 3 cm latura unui pătrat,acesta ar deveni de șase ori mai mică decât perimetrul pătratului.
Care este semiperimetrul pătratului?​

Answer 1

Given : If   the side of a square reduced  by 3 cm, it would become six times smaller in the perimeter

To Find :  semi perimeter of the square

Solution:

Let say side  of square = a  cm

Perimeter = 4a    cm

side of a square reduced  by 3 cm

New side = a - 3 cm

New perimeter =  4(a - 3)  cm

4(a - 3)   = 4a/6

=> 6 (a - 3) = a

=> 6a - 18  = a

=> 5a  = 18

=>  a  = 18/5

=> a = 3.6

Perimeter of square = 4a = 4 * 3.6  = 14.4 cm

Semi Perimeter of square =  14.4/2  = 7.2  cm
