Question

Twice of perimeter of a triangle is 30 cm. If all sides of triangle are equal. Find the measure of all the sides. What type of triangle you obtain?

Answer 1

Answer:

Measure of all sides - 5 cm each

Type of triangle - Equilateral triangle

Step-by-step explanation:

Twice of perimeter of triangle = 30 cm

=> 2 × perimeter = 30 cm

=> perimeter = 30÷2 cm

=> perimeter = 15 cm

All sides are equal, so

side 1 = side 2 = side 3

Let us consider side as x, all three side will x, because all are equal.

Sum of all sides = perimeter

=> x + x + x = 15 cm

=> 3x = 15 cm

=> x = 15/3 cm

=> x = 5 cm

Because all sides are equal, so all sides will measure 5 cm.

Because all sides are equal, we will obtain a equilateral triangle.
