Question

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

Answer 1

Let the base of the triangle be x.

So, other two sides would be (3 + x) and (x - 3)

We know that,

Perimeter = sum of all sides

72 = x + 3 + x + x - 3

3x = 72

x = 24

Thus, base = 24 cm.
