A student is given the rectangle and the square shown. The student states that the two figures have the same perimeter. Is the student correct? Complete the explanation to explain your reasoning.
x + 18
X +9
х
X +9
the lengths of its sides.
The student is select) The perimeter of a figure is found by (select)
For the rectangle, the perimeter is
For the square, the perimeter
is

correct

Step-by-step explanation:

The perimeter is the sum of the sides.

Rectangle ( opposite sides are congruent ), thus

perimeter = 2x + 2(x + 18) = 2x + 2x + 36 = 4x + 36

Square ( sides are congruent ), thus

perimeter = 4(x + 9) = 4x + 36

The perimeters are the same, so the student is correct
