Answer:

Step-by-step explanation:

Given,

The area of a rectangular sheet of aluminium = 400cm²

Breadth of the  sheet = 16cm

The formula for finding the area of a rectangle=l×b

⇒l×16=400

⇒l=400/16

⇒l=25

The formula for finding the perimeter of the rectangle=2×(l+b)

=2×(25+16)

=2×41

=81

Therefore the perimeter of the rectangular sheet is 81cm
