Chapter 3: Q17. (page 139)

Find the perimeter of the triangle, if all the sides of the triangle are equal in length.

Short Answer

Expert verified

The perimeter of the triangle is39鈥�unit.

Step by step solution

01

. Apply the concept of equilateral triangle and perimeter of the triangle

In this type, in equilateral triangle its properties is all the sides of the triangle are equal & the perimeter is3脳side.

02

Step  2. Finding the length of the sides of the triangle

Since,

Let the length of the side be x.

The sides of the triangles are 2x+5,4x鈭�3.

Now, from the property of the triangle, take the variable and constant in separate side and then do mathematical operations.

2x+5=4x鈭�32x鈭�4x=鈭�5鈭�3鈭�2x=鈭�8x=82x=4

03

Step  3 .Finding the perimeter 

Now, the length of the side is2x+5=2(4)+5=8+5=13

So, the perimeter is ,

P=3脳sideP=3脳13P=39鈥�unit
