Question

A wire is (7x – 3) metres long. A length of (3x – 4) metres is cut for

use. Now, answer the following questions:


If this left out wire is used for making an equilateral triangle.

What is the length of each side of the triangle so formed?​

Answer 1

Answer:

Step-by-step explanation:

Given,

length of wire =(7x−3)m

and wire cut for use has length =(3x−4)m

Left wire =(7x−3)−(3x−4)=(4x+1)m

(b) Left wire =(4x+1)m

Perimeter of equilateral triangle = Length of wire left

⇒ 3×side=4x+1

⇒ side=  3(4x+1) =  3

​  

(4x+1)m

Answer 2

Answer:

(4x+1)/3

Step-by-step explanation:

(7x-3)-(3x-4)=7x-3-3x+4=4x+1

length of each side=(4x+1)/3
