Question

the area of a rectangular sheet of aluminium is 400 cm^2.if the breadth of the sheet is 16cm,find its length.Also find the perimeter of the aluminium sheet.​

Answer 1

Answer:

We know that are of rectangle= length x breadth

So, length x 16 = 400

So, Length= 400/16 = 25cm

Perimeter= 2(L+B)

=2(25+16) = 2 x 41 = 82cm

Answer 2

Answer:

We know that are of rectangle= length x breadth

So, length x 16 = 400

So, Length= 400/16 = 25cm

Perimeter= 2(L+B)

=2(25+16) = 2 x 41 = 82cm
