A wire is in the shape of a square of side 10 cm. If the wire isrebent into a rectangle of length 12 cm, find its breadth. Which enclosesmore area, the square or the rectangle?

Answer» perimeter of square `= 10 xx 4 = 40cm`
perimeter of rectangle = `2(l+b)`
`40 = 2(12+b)`
`b + 12 = 20`
`b = 8cm`
area of rectangle = `l xx b`
`= 12 xx 8 = 96 cm^2`
`area of square = 10^2 = 100 cm^2`
`:.`square `>` rectangle
