A rectangle is a two-dimensional shape with four sides and four angles. It has two pairs of equal-length sides that are parallel to each other, and all of its interior angles are right angles.
To find the area of a rectangle, you multiply the length by the width. The formula for area is A = l * w, where A is the area, l is the length, and w is the width. For example, if a rectangle has a length of 5 units and a width of 3 units, its area would be 5 * 3 = 15 square units.
The perimeter of a rectangle is the total distance around its outer edges. To find the perimeter, you add together the lengths of all four sides. The formula for perimeter is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width. For instance, if a rectangle has a length of 5 units and a width of 3 units, its perimeter would be 2(5) + 2(3) = 16 units.
No, a rectangle cannot have equal sides. By definition, a rectangle has two pairs of equal-length sides that are parallel to each other, but the two pairs must be of different lengths. If all four sides of a shape are equal, it would be classified as a square, not a rectangle.
A rectangle has two lines of symmetry - one horizontal and one vertical. This means that if you were to fold the rectangle in half along either of these lines, the two halves would match up perfectly. Additionally, a rectangle has rotational symmetry of 180 degrees, meaning it looks the same when rotated 180 degrees around its center point.
