Answer:
448 sq.ft
Step-by-step explanation:
The following figure is a trapezium,
So Given,
Parallel sides of the trapezium = 17ft and 39ft
Height of the trapezium = 16ft
Therefore,
Area of the trapezium
[tex] = \frac{1}{2} \times (sum \: of \: parallel \: sides) \times height[/tex]
[tex] = \frac{1}{2} \times (17ft + 39ft) \times 16ft[/tex]
[tex] = \frac{1}{2} \times 56ft \times 16ft[/tex]
[tex] = 56ft \times 8ft[/tex]
[tex] = 448 {ft}^{2} [/tex]
Hence,
448 sq.ft is the area of the trapezium (Ans)
