Respuesta :
The area of a rectangle whose length is 5.6 cm and the width is 2.1 cm to two significant figures is 12 cm ².
Further Explanation
Area
- Area is a measure of how much space is occupied by a given shape.
- Area of a substance is determined by the type of shape in question.
For example;
Area of a rectangle is given by; Length multiplied by width
Area of a triangle = 1/2 x base x height
Area of a circle = πr². where r is the radius of a circle,
Area of a square = S², Where s is the side of the square.etc.
Perimeter
- Perimeter is defined as the distance along a two dimension shape. Perimeter of different shapes is given by different formulas
- For example
The perimeter of a rectangle = 2(length+width)
The perimeter of a triangle = a+b+c; where a, b and c are the sides of the triangle. etc.
In this question
The rectangle has a;
Length = 5.6 cm
Width = 2.1 cm
Area of a rectangle = length × width
= 2.1 cm × 5.6 cm
= 11.76 cm²
The area of the rectangle to two significant figures is 12 cm²

The area of the rectangle is 12 cm².
Rectangle
It is a polygon that has four sides and four corners. The sum of the internal angle is 360 degrees. In rectangle opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at mid-point.
Given
A rectangle that is 2.1 cm wide by 5.6 cm long.
To find
You do not round your answer to two significant figures, your answer will fall outside of the grading tolerance and be graded as incorrect.
Area of rectangle
Area = length x width
Area = 2.1 x 5.6
Area = 11.76
When the value after the point is more than 5 then we take the next number.
So the area of the rectangle is 12 cm².
