the base of an isosceles triangle is 26 cm. if the perimeter is 72 cm. find the lenght of each of the eqaul sides
each side is half of what's left when we subtract the base:
(72-26)/2 = 23cm
230sq.cm
To find the length of each of the equal sides of an isosceles triangle, we need to use the perimeter and the length of the base.
Let's denote the length of each equal side as "x" cm.
We know that the perimeter of a triangle is equal to the sum of the lengths of all three sides. In this case, the perimeter is 72 cm.
Given that the base of the isosceles triangle is 26 cm, we can set up an equation using the information we have:
Perimeter = Base + 2(equal sides)
72 cm = 26 cm + 2x
To find the length of each equal side, we need to solve for "x".
Rearranging the equation, we have:
2x = 72 cm - 26 cm
2x = 46 cm
Now, divide both sides of the equation by 2 to solve for "x":
x = 46 cm / 2
x = 23 cm
Therefore, the length of each equal side of the isosceles triangle is 23 cm.
