The perimeter of a square whose length is 12.0 m is 48 cm.
<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.
<h3>Perimeter </h3>
- 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 case;
We are given one side of a square as 12.0 cm
But Perimeter of a square is given by; 4 × s
Thus; Perimeter = 4 × 12 units
= 48 units
