The expression that cannot be used to find either the area or the perimeter of a rectangle is: 7 + 12
What is the area and the perimeter of a rectangle?
A rectangle is a 2-dimensional quadrilateral with four right angles that sum up to 360 degrees. A rectangle has two diagonals which bisect each other at right angles.
The area of a rectangle is the product of the width and the length.
Area of a rectangle = length x width
12 x 7 = 84 units²
7 . 10 + 7 . 2
70 + 14 = 84
The perimeter of a rectangle is the distance round the rectangle.
Perimeter of a rectangle = 2 x (length + width)
2 x (12 + 7)
2 x 19 = 38 units
7 + 12 + 7 + 12 = 38
2 . 7 + 2 . 12
14 + 24 = 38
