find the area of trapezoid klmn. round your answer to the nearest tenth if necessary.
(image of trapezoid klmn with side lengths: lm = 5.4 in, mn = 3.3 in, nk = 7.9 in, height (distance between the two parallel sides) = 4.4 in, and the length of the longer parallel side = 13.2 in)

Explanation:

Step1: Identify trapezoid formula

Area = $\frac{1}{2} \times (b_1 + b_2) \times h$

Step2: Assign values

$b_1 = 5.4$ in, $b_2 = 7.9$ in, $h = 4.4$ in

Step3: Calculate sum of bases

$5.4 + 7.9 = 13.3$ in

Step4: Compute area

$\frac{1}{2} \times 13.3 \times 4.4 = 58.12 \approx 58.1$ in²

Answer:

58.1
