From the given problem, the length of Olivia's rectangular garden is 12.5 m and the breadth (width) is 8.4 m.

Olivia's garden is rectangular, 12.5 meters long and 8.4 meters wide. What is its area?

Answer: 105 square meters (or $105\text{ m}^2$ )

From the given problem, the length of Olivia's rectangular garden is $12.5\text{ m}$ and the breadth (width) is $8.4\text{ m}$ .

The area of a rectangle is found by multiplying its length by its breadth.

Multiplying $12.5$ by $8.4$ , we get $105$ . Since the dimensions are in meters, the unit of area is square meters ( $\ ext{m}^2$ ).
