Answer 2

fisrt find the perimeter of the triangle... iit will give u the length of the wire..

since the perimeter is equal to the sum length of all sides...
the perimeter of the triangle will be
(8 + 8 + 8 ) = 24 cm
which means that the length of the wire is 24 cm..

now when it shaped in to a rectangle...
the perimeter of the rectangle = the length of the wire...
= 24 cm
and the slandered way of finding the perimeter of a rectangle is
(2 x width ) + ( 2 x length )
if
length = l and width = w
then
perimeter = 2l + 2w

since we know length = l = 8
then
perimeter = (2x8) + 2w
24 = 16 + 2w
2w = 8
w = 4 cm = width

got it :) ?
