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. both shapes have a perimeter of 12 inches. an equation for the perimeter of the shapes is 12. b. the triangle has a greater 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 square perimeter

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 triangle perimeter

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:

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