Ariel's garden is planted in the shape of a square and has an area of 81 square feet. If she plans to put a fence around the perimeter of the garden, how much fencing will she need?

Question

A) 18 ft, B) 41 ft C) 36 ft D) 9Ft

I came up with D 9 foot but apparently I didn't work it correctly. Could someone explain how to work this.

Thank you

Answer 1

You are correct that each side is 9 feet.

But that wasn't the question. How much fence do you need to fence all 4 sides of 9' each?
