Question

find the surface area of each (use π = 3.14) 1) surface area =

Explanation:

Step1: Calculate the area of the parallelogram

The formula for the area of a parallelogram is \(A = base\times height\). Here, the base is \(6.3\) yd and the height is \(18.5\) yd.
\(A_{parallelogram}=6.3\times18.5 = 116.55\) \(yd^{2}\)

Step2: Calculate the area of the right - triangle

The formula for the area of a triangle is \(A=\frac{1}{2}\times base\times height\). Here, the base is \(11.7\) yd and the height is \(14.3\) yd.
\(A_{triangle}=\frac{1}{2}\times11.7\times14.3=\frac{11.7\times14.3}{2}=\frac{167.31}{2}=83.655\) \(yd^{2}\)

Step3: Calculate the total surface area

The total surface area \(A = A_{parallelogram}+A_{triangle}\)
\(A=116.55 + 83.655=200.205\) \(yd^{2}\)

Answer:

\(200.205\) \(yd^{2}\)
