Question

1. A wire is (7x − 3) metres long. If a length of (3x − 4) metres is cut for use, answer
the following:
(a) How much length of wire is left? (write algebraic expression)
(b) If this left out wire is used for making an equilateral triangle. What is the
length of each side of the equilateral triangle? (write algebraic expression)
(c) Find the original length of the wire if x = 2.

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)

=
