Respuesta :

We have been given an image of a trapezoid. We are asked to find the area of the given trapezoid.

We will use area of trapezoid formula to solve our given problem.

[tex]A=\frac{1}{2}(a+b)\times h[/tex], where,

A = Area of trapezoid,

a and b = Parallel sides or bases of trapezoid.

h = Height of trapezoid.

We can see that one base is 45 feet. The other base would be 45 plus 15 feet that is [tex]45+15=60[/tex].

Now we will use Pythagoras theorem to find the height of the trapezoid as:

[tex]h^2=17^2-15^2[/tex]

[tex]h^2=289-225[/tex]

[tex]h^2=64[/tex]

[tex]\sqrt{h^2}=\sqrt{64}[/tex]

[tex]h=8[/tex]

[tex]A=\frac{1}{2}(45+60)\times 8[/tex]

[tex]A=(105)\times 4[/tex]

[tex]A=420[/tex]

Therefore, the area of the given trapezoid is 420 square feet.
