Detailed Solution

The area of a rectangle whose length is 12.5m and breadth is 8dm is

10 m 2

.
We know that area of a rectangle is

l × b

, where l is the length and b is the breadth.
First, we will convert the units into a single unit.
1m=10dm
1dm=

110 m

8dm=

810 m

or 0.8m
So,
Area of rectangle=

l × b

= 12.5 m × 0.8 m

10 m 2

Hence, the correct answer is
