Final answer:
The area of a rectangle with a length of 6 m and a height of 7 m is 42 sq. m, which corresponds to option (a).
Step-by-step explanation:
The subject of this question involves calculating the area of a rectangle, which is a fundamental concept in Mathematics. To find the area, you multiply the length of the rectangle by its width (or height). In this instance, the rectangle has a length of 6 meters and a height of 7 meters. Therefore, the area is calculated as follows:
Area = Length × Height
Area = 6 m × 7 m
Area = 42 square meters (sq. m)
The area of the rectangle is 42 sq. m, which means that option (a) is the correct answer. When asked to round to the nearest square unit, you would not need to round because 42 is already an integer.
