# A wire is cut into several small pieces. Each of the small pieces is bent into a square of side 2cm. If the total area of the small squares is 28 square cm, what was the original length of the wire?

Answer :

Side of square by bending small piece of wire = 2 cm.

Total area of small squares = 28 sq.cm

Number of small squares = 28 / 4

= 7

Perimeter of small square = 4 × 2

= 8 cm

Perimeter of 7 small squares = 8 × 7

= 56 cm

Hence original length of wire = 56 cm.
