\large\bf{\underline{Answer:}}

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎
\large\bf{ = 3000 \:ft^2}

__________________________________________


\large\bf{\underline{Given:}}

  • A 3 dimensional figure with 5 sides
  • it has 3 rectangles with dimensions 28 ft and 25 ft
  • And 2 triangles with base =30 ft and height = 20 ft


\large\bf{\underline{To\: find:}}

  • Total surface area of figure


\large\bf{\underline{Therefore:}}


\bf{area \:of\: figure}

‎ㅤ
{\bf = area \:of \:3\: rectangles + 2 \: triangles}


\large\bf{\underline{Formulas:}}


\boxed{\bf\pink{area\:of\: triangle= (1)/(2)* base* height}}


\boxed{\bf\pink{area\:of\: rectangle=length* breadth}}

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎
\large\bf{= 3* (28 * 25 )+ 2((1)/(2) * 30 * 20)}

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎
\large\bf{= 3 * 800 + 2 * 300}

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎
\large\bf{=2400+ 600}

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎
\large\bf{= 3000}

__________________________________________


\large\bf{\underline{Hence,}}

Area of given figure

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎
\huge\mathfrak{= 3000\: ft^2}
