Answer:

17.7% rounded to the nearest tenth

Explanation:

Well to find the percent of space the trapezoid takes up we need to find both areas.

To find the area of a Rectangle we do l*w.

So the l is 30 and the w is 16 so,

30*15 = 480m^2

To find the area of a Trapezoid
(b1 + b2)/(2)h.

So b1 is 20 and b2 is 14,

14 + 20 = 34

34/2 = 17

17 * h

17 * (5) = 85m^2

So now we make a fraction of the areas of the trapezoid and rectangle,


(85)/(480)

Now we simplify,

85/5 = 17

480/5 = 96

So 17/96 is in its simplest form so now we do 17/96 which is 0.1770833333

So to the following into a percent we move the decimal places 2 places to the right which is about 17.7% rounded to the nearest tenth.

Answer: about 17.7%

Explanation:

The area of a trapezoid is ((b1+b2)/2)*h

Thus, the area of the trapezoid is 85 meters squared. Thus, because the garden is 480 meters squared, the trapezoid occupies 85/480 of the garden, or about 17.7 percent.

Hope it helps <3
