Question

the base of an isosceles triangle is 4 by 3 cm the perimeter of the triangle is 4 2/5 find the length of the other two sides of the triangle​

Answer 1

Answer:

We know that,

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

The perimeter of a triangle = Sum of the lengths of all three sides

Let's form a linear equation for the given problem statement.

Base of an isosceles triangle = 4/3 cm

Let the equal sides measure as x cm each

Therefore, Perimeter of the triangle = x + x + 4/3 =

4

2

15

Solving the above equation

⇒ 2x + 4/3 =

4

2

15

⇒ 2x = 62/15 - 4/3

⇒ 2x = 42/15

⇒ x = 21/15

⇒ x = 7/5

Therefore, the length of the remaining equal sides of the triangle is 7/5 cm
