Let's call the length of the equal sides of the isosceles triangle "a". Since the perimeter is less than 24 cm, we can set up the following inequality:
2a + 9 < 24
Simplifying the inequality, we get:
2a < 15
a < 7.5
Since "a" represents the length of a side of the triangle, it must be a whole number. Therefore, the lowest possible value of "a" is 7. Hence, the lowest value of x is 7.
An isosceles triangle has sides of length xcm xcm and 9cm. It perimeter is less than 24cm and x is a whole number. Find the lowest value of x
