| A rectangle has opposite sides equal and parallel.
The area of the rectangle is calculated by multiplying the length of the figure by its width.
Let’s write down the formula for determining the area of a rectangle:
S = a * b;
S is the area of the rectangle;
a and b – its length and width.
A square is a rectangle with the same sides.
The formula for determining the area of a square is:
S = a * a = a ^ 2;
S is the area of the square;
a – the length of the side of the figure.
Find the area of the square:
S = 6cm * 6cm = 36cm2.
Rectangle area:
S = 12cm * 3cm = 36cm2.
Answer: the areas of a square and a rectangle are equal.
