Question

the perimeter of a triangle is 72cm. if one of the side is 3 cm greater than the base and the other side is 3 cm smaller than the place to find the base of the triangle​

Answer 1

Perimeter of triangle= 72 cm

let base = x

Side 1 = x+3

Side 2 = x-3

$therefore,\\ x +(x+3)+(x-3) = 72\\3x = 72\\x = 72/3\\x = 34$

So, base = 34 cm
