Kyla makes a triangular school pennant. The area of the
triangle is 180 square inches. The base of the pennant is z inches long. The
height is 6 inches longer than twice the base length. The base and height can
be solve using the formal A =bh/2
Since b = z and h = 6 + 2z
180 = z(6+2z) /2
B =Z =12 in
H = 30 in
Using the Heron's formula, the area of the triangle is: D. 95 square inches.
<h3>What is the Heron's Formula?</h3>
Area = √[s(s - a)(s - b)(s - c)] where s is half the perimeter, or (a + b + c)/2.
Given the following:
s = semi-perimeter = 1/2(50) = 25 in.
a = length of side a = 22 in.
b = length of side b = 13 in.
c = length of side c = 50 - 22 - 13 = 15 in.
Plug in the values
Area = √[25(25 - 22)(25 - 13)(25 - 15)]
Area = √[25(3)(12)(10)]
Area ≈ 95 square inches.
