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.
<h2>Further Explanation </h2><h3>Area </h3>
- 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
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
