Approximately how many square inches of fabric were used to make the triangular flag? 15 square inches 76 square inches 186 squa

Law Incorporation [45]

The area used to make the triangular flag is 15 square inches.

Given

Two of the sides are 8 in.

Lila made a triangular flag to cheer on her favorite sports team.

The perimeter of the flag is 20 inches.

<h3>What is Heron’s formula?</h3>

Semi-perimeter is equal to the sum of all three sides of the triangle divided by 2.

Then,

The value of S is;

$\rm S = \dfrac{20}{2}\\\\S =10$

Therefore,

The area used to make the triangular flag is;

$\rm Area = \sqrt{s(s-a)(s-b)(s-c)} \\\\A rea= \sqrt { (10)(10-8)(10-8)(10-4) }\\\\Area = \sqrt{10 \times 2 \times 2\times 6}\\\\Area = \sqrt{240}\\\\Area = 15.49$

Hence, the area used to make the triangular flag is 15 square inches.
