Question

The area of a rectangular sheet of aluminium is 400 sq.cm.. If the breadth of the sheet is 16cm,find its length. Also find the perimeter of the aluminium sheet.

Answer 1

length 25 cm
perimeter 82 cm

Answer 2

Answer:

Perimeter (P)=52\frac{2}{3}\: cm

Step-by-step explanation:

Side \:of \:a \:square (a)\\=13\frac{1}{6}\:cm\\=\frac{79}{6}

Perimeter (P) = 4a

= 4\times \frac{79}{6}\\=2\times \frac{79}{3}\\=\frac{158}{3}\\=52\frac{2}{3}\: cm

Therefore,

Perimeter (P)=52\frac{2}{3}\: cm
