Question

andrew drew a square with each side measuring 3 inches. lindsay drew a triangle with each side measuring 4 inches. which shape has a greater perimeter? write an equation to help explain your answer. select the correct answer below, and fill in the answer boxes to complete your choice. (use the operation symbols in the math palette as needed.) a. the triangle has a greater perimeter of inches. an equation for the perimeter of the shapes is b. both shapes have a perimeter of inches. an equation for the perimeter of the shapes is c. the square has a greater perimeter of inches. an equation for the perimeter of the shapes is

Explanation:

Step1: Calculate perimeter of square

The formula for the perimeter of a square is $P = 4s$, where $s$ is the side - length. Given $s = 3$ inches, so $P_{square}=4\times3 = 12$ inches.

Step2: Calculate perimeter of equilateral triangle

The formula for the perimeter of an equilateral triangle is $P = 3s$, where $s$ is the side - length. Given $s = 4$ inches, so $P_{triangle}=3\times4=12$ inches.

Answer:

B. Both shapes have a perimeter of 12 inches. An equation for the perimeter of the square is $P = 4\times3$. An equation for the perimeter of the triangle is $P = 3\times4$.
