Question

The area of rectangular sheet is 8 2/5 square cm and its breadth is 2 4/5 cm find its perimeter?​

Answer 1

Answer:

area of the rectangular sheet is 8 2/5 sq cm

breadth =2 4/5 cm

length =area/breadth=8 2/5/2 4/5 cm

=42/5×5/14 cm

=3cm

perimeter =2(length+breadth)

=2(3+2 4/5) cm

=2(3+14/5)cm

=2(15+14/5)cm

=2×29/5cm

=58/5cm

=11 3/8 cm
