A rectangle has a length of 14 m and a width of 9 m. Find its area and perimeter.

For a rectangle, the area is:
A = length × width

Substitute the dimensions:
A = 14 × 9
A = 126

So the area is 126 m².

The perimeter of a rectangle is:
P = 2(length + width)

Substitute the dimensions:
P = 2(14 + 9)
P = 2(23)
P = 46

Therefore, the rectangle has an area of 126 m² and a perimeter of 46 m.
