- Step-by-step explanation:
<em>Heron formula</em>
<em>A = √p(p - a)(p - b)(p - c)</em>
<em>a = 9 ; b = 15 ; c = 20</em>
<em>p = (a + b + c)/2 = (9 + 15 + 20)/2 = 44/2 = 22</em>
<em>A = √22(22-9)(22-15)(22-20)</em>
<em>= √22×13×7×2</em>
<em>= √4004</em>
<em>≈ 63,27</em>
<em>≈ 63.30 ft²</em>
9a-27b you must multiply 9 to everything
