Q: If the perimeter of an isosceles triangle is 24 cm and the lengths of the two equal sides are 10 cm each, what is the length of the base?

Solution: The perimeter is the sum of all sides. Therefore, base = 24 - (10 + 10) = 4 cm.

Steps: 6

Step 1: Understand that the perimeter of a triangle is the total length around the triangle, which is the sum of all its sides.
Step 2: Identify the lengths of the two equal sides of the isosceles triangle. In this case, each equal side is 10 cm.
Step 3: Since there are two equal sides, calculate their total length: 10 cm + 10 cm = 20 cm.
Step 4: Now, use the perimeter to find the length of the base. The perimeter is given as 24 cm.
Step 5: Subtract the total length of the two equal sides from the perimeter: 24 cm - 20 cm = 4 cm.
Step 6: Therefore, the length of the base of the triangle is 4 cm.
