therefore the permieter of the rectangle is also = 24
perimeter of a rectangle = 2(length) + 2(width) = 2x + 2w = 2w + 2x
thus, 2w + 2x =24

how can the length of the wire be equal to the perimeter??

ok..suppose...u take a 30cm wire...fold it to make a circle...a triangle...a square...whatever,,.,doesnt matter
u havent added any extra wire nor have u removed a part of the wire....the perimeter will be equal to the length of wire taken rite?
dont confuse it with the area....u'm talking abt the perimeter....
