Question

The area of a rectangular sheet of aluminum is 400cm square If the breadth of the sheet is 16cm,find its length.also find the perimeter of aluminum sheet answer step by step

Answer 1

Step-by-step explanation:

area =l×b

here area =400 cm

it's breadth =16cm

so l=area/breadth

lengh=400/16=25

Answer 2

Answer:

Lenght = 25cm

Perimeter = 82cm

Step-by-step explanation:

Area = Lenght * Breadth

400 = Lenght*16

Lenght = 400/16 = 25cm

Perimeter of rectangle = 2*(Lenght + Breadth)

= 2*(16+25) = 2*(41) = 82 cm.
