Answer:
D. 10 square units
Step-by-step explanation:
The area of a triangle is given by the formula ...
A = 1/2bh
__
This triangle has a base of 4 units and a height of 5 units. (These dimensions can be counted from the graph, or found by subtracting coordinate values.) Its area is ...
A = 1/2(4 units)(5 units) = 10 square units
_____
<em>Additional comment</em>
The first two coordinates lie on the line x=0. The length of that segment is the difference of the y-values: 4 -(-1) = 5.
The first and last coordinates lie on the line y=-1. The length of that segment is the difference of the x-values: 4 -0 = 4.
Answer:
A is 16 and B is -243 and my calculator is a smart calulator
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
