Question

A square has a side length of (x+3) centimeters. If the perimeter is 24 centimeters, what is the side length of the square? (Hint: to find

the perimeter of a square, you add up all the lengths of the sides).
A.Зcm
B.7cm
C. 9cm
D.14cm

Answer 1

3

Explanation:

A square has 4 equal sides

so

4(x+3) = perimeter = 24

4x+12 = 24

4x = 12

x=3

Answer 2

3 cm

Explanation:

4(x + 3) = 24

4x + 12 = 24

4x = 12

x = 3 cm

**multiply by 4 because a square has 4 equal sides***
