Question

A wire is in the shape of a square of side is 12 CM. If the wire rabent into a rectangle of length of 70 CM Find its breadth enclose more than the square or the rectangle

Answer 1

i think the length is 7 cm
$s = 12cm$
as the same wire is bent to a rectangle

perimeter of square = perimeter of rectangle
i.e
4 x 12 = 2(7+b)
48 = 14 + 2b
34= 2b
b= 17
