Question

Find the perimeter and area of a rectangle having : length =8 meter , Breadth=9 decimeter

Answer 1

1 meter=10dm
8meter=80dm

perimeter of the rectangle=2(l×b)
perimeter of the rectangle =2(80dm+9dm)
perimeter of the rectangle =2(89dm)
perimeter of the rectangle=178dm


Area of the rectangle=l×b
area of the rectangle=80dm×9dm
area of the rectangle=720 dm^2
