If the width and length of the rectangle are 3 cm and 7 cm. Then the perimeter of the rectangle is 10 cm.
It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.
Let L be the length of the rectangle and W be the width of the rectangle.
Then we have
4W + 3L = 33 ...1
2W + L = 13 ...2
Then by the equations 1 and 2, we have
W = 3 and L = 7
Then the perimeter of the rectangle will be
Perimeter = W + L
Perimeter = 3 + 7
Perimeter = 10 cm
