Data

base = 12 m

height = 6.01 m

Formula

Area of a rectangle = base x height

Process

1.- Find the area of the rectangle

  Area = 12 x 6.01 = 72.12 m²

2.- Apply the rule of significant figures

"Round the answer to the shortest number of significant digits in the numbers you are multiplying"

- 6.01 has three significant figures

- 12     has two significant figures

So, the answer is 72
