Question

One of the equal sides of an isosceles triangle is 4.6 cm. If the perimeter of the triangle is 15.2cm,find the remaining side

Answer 1

Answer:

The other side is 6 cm....

Step-by-step explanation:

Let the sides of the isosceles triangle be 4.6 cm, 4.6 cm and x cm ( since it's isosceles).

Now, the perimeter = side + side + side = 15.2 cm (given)

=>  4.6 + 4.6 +x =15.2

=> x = 15.2 - 9.2 => x = 6 cm

Answer 2

Answer:

Step-by-step explanation:

soln,

given

Length of an two equal sides of an isosceles triangle=4.6cm

perimeter of an isosceles triangle = 15.2 cm

remaining side of isosceles triangle = ?

We know that ,

2a+b = p

or,2*4.6+b=15.2

or,9.2+b=15.2

or,b=15.2-9.2

so, b = 6cm

hence,the remaining side of an isosceles triangle is 6cm
