Question

perimeter of a triangle is 64cm one side is 24 second side is 20 cm longest than three side. Find the second and third side.​

Answer 1

Required Answer :

• Second side = 30 cm
• Third side = 10 cm

Given :

• Perimeter of the triangle = 64 cm

• One of the side of the triangle = 24 cm

• The second side is longer than the third side than 20 cm.

To find :

• Second and third side of the triangle

Solution :

Let,

• Third side of the triangle = x
• Second side of the triangle = x + 20 cm

Using formula,

• Periemter = a + b + c

where,

• a, b and c are the three sides of the triangle

Substituting the given values :-

→ 64 = x + x + 20 + 24

→ 64 = 2x + 44

→ 64 - 44 = 2x

→ 20 = 2x

→ 10 = x

Substituting the value of 'x' in the sides of the triangle :-

→ Third side = x

→ Third side = 10 cm

→ Second side = x + 20

→ Second side = 10 + 20

→ Second side = 30 cm
