What is the answer to this

Answer:
193 m²
Step-by-step explanation:
Let us separate the figure into three parts:
One right angled triangle, square and rectangle.
right angle triangle having height(h) = (10+5+3)m = 18m
base of right angled triangle(b) = 25-(8+4)m = 13m
length of square(l) = 8m
length of rectangle (a) = 4m
breadth of rectangle (w) = 3m
[tex]total \: area \: of figure = area \: of \: triangle + area \: of \: square + area \: of \: rectangle[/tex]
[tex] = \: ( \frac{1}{2} \times b \: \times h ) \: + ({l}^{2} )\: + (a \: \times w)[/tex]
[tex] = (\frac{1}{2} \times 13 \times 18) + {8}^{2} + (4 \times 3)[/tex]
[tex] = 193 \: {m}^{2} [/tex]
