Hello!
PERIMETER:
To find the perimeter of the trapezoid, simply add all sides together.
15 + 5 + 9 + 5 = 34
The perimeter is
____________________________________________________________
AREA:
A = h(
+
)
A = 4(9 + 15)
A = 4(24)
A = 2(24)
A = 48
The area of the trapezoid is
Answer:
Step-by-step explanation:
Look at the picture.
The formula of an area of a triangle:
<em>b</em><em> - base</em>
<em>h</em><em> - height</em>
<em />
We need a length of a height.
Use the Pythagorean theorem:
We have:
Substitute:
<em>subtract 25 from both sides</em>
Calculate the area:
Answer:
(a)
(b)
