Question

jessica is planning to build a triangular garden with a border made out of wood. two of the sides will be 17.2 feet in length. the other side will be 3.9 feet. she has a total of 39 feet. does she have enough wood to make the border? explain.
the total length of the border is (square) feet. this is (square) the length of wood jessica has. she (square) enough wood to make the border.
(type a whole number or a decimal)

Explanation:

Step1: Calculate the perimeter of the triangular garden

The perimeter \(P\) of a triangle is the sum of the lengths of its sides. Given two sides of length \(a = 17.2\) feet and \(b=17.2\) feet, and the third side \(c = 3.9\) feet.

$$P=a + b + c=17.2+17.2 + 3.9$$

Step2: Perform the addition

First, add \(17.2+17.2=34.4\). Then add \(34.4+3.9\).

$$34.4+3.9 = 38.3$$

Answer:

The total length of the border is \(38.3\) feet. This is less than the length of wood Jessica has. She has enough wood to make the border.
