Question

the base of an isosceles triangle is 4by3 cm the perimeter of the triangle ​

Answer 1

Answer :-

• The perimeter of the isosceles triangle is (6x + 4)/3 cm.

To find :-

• The perimeter of the isosceles triangle.

Step-by-step explanation :-

• Here, it is given that the base of an isosceles triangle is 4/3 cm. We have to find the perimeter of the triangle!

We know that :-

• In an isosceles triangle, two of the sides are equal.

Let :-

• The two equal sides of the triangle be "x" and "x".

Now, we know that :-

$\underline{\boxed{\sf{Perimeter_{(isosceles \: triangle)} = 2a + b}}}$

Where :-

• 2a = equal sides
• b = unequal side.

Here :-

• Equal sides = "x" and "x".
• Unequal side = 4/3 cm.

Therefore :-

$\longrightarrow \rm Perimeter = x + x + \dfrac{4}{3}$

$\longrightarrow \rm Perimeter = 2x + \dfrac{4}{3}$

$\longrightarrow \rm Perimeter = \dfrac{2x}{1} + \dfrac{4}{3}$

$\longrightarrow \rm Perimeter = \dfrac{(3 \times 2x) + (1 \times 4)}{3}$

$\longrightarrow \rm Perimeter = \dfrac{(6x + 4)}{3}$

Hence :-

• The perimeter of the isosceles triangle is (6x + 4)/3 cm.
