Question

the base of the isosceles triangle is 5/3cm. if the perimeter of the triangle is(4) 3/6 cm. find the remaing lenght of equal sides​

Answer 1

GivEn:

• The base of the isosceles triangle is 5/3cm.
• The perimeter of the triangle is(4) 3/6 cm.

To find:

• The remaining length of equal sides?

Solution:

• Let's consider ABC is a triangle.

Where,

• Base = 5/3cm
• Perimeter = 4 3/6 cm

• Let other two sides of the isosceles triangle be x.

{ Two sides of an isosceles triangle are equal. }

⠀⠀━━━━━━━━━━━━━━━━━━━⠀

« Now, Finding the equal sides (x),

We know that,

• Perimeter = Sum of all sides.

→ 27/6 = x + x + 5/3

→ 27/6 = 2x + 5/3

→ 2x = 5/3 - 27/6

Finding a common denominator,

→ 2x = 10/6 - 27/6

→ 2x = -17/6

→ x = -17/6 × 1/2

→ x = -17/12

∴ Hence, The length of remaining two sides is -17/12.
