Question

The sides of an isosceles triangle are 1/3 cm , 1/2 cm and 1/2 cm . What is the perimeter of the triangle?​

Answer 1

Answer : Thus x=3 and Perimeter of a triangle=22 square units

Step-by-step explanation:

In isosceles triangle two sides are equal,

So,

3x-1=2x+2

x=3

Perimeter=sum of all sides

=3x-1+2x+2+2x

=7x+1

Substituting value of x

Perimeter=7(3)+1

=21+1

=22

Thus x=3 and Perimeter of a triangle=22 square units

Answer 2

Answer:

Perimeter of any shape = Sum of all sides

= 1/3 + 1/2 + 1/2

= 1/3 + 1

= 1 + 1/3 (used commutative property here)

= 1 ⅓ cm or 4/3 cm

Therefore, perimeter of triangle is 1 ⅓ centimeters
