Step-by-step explanation:
<u>ANSWER: </u>
The area of the triangle with vertices at (0, – 2), (8, – 2), and (9, 1) is 12 square units.
<u>SOLUTION:
</u>
Given, vertices of the triangle are A(0, -2), B(8, -2) and C(9, 1).
We have to find the area of the given triangle.
We know that,


Here in our problem, 
Now, substitute the above values in the formula.




Hence, the area of the triangle is 12 sq units.
Answer:
<h2>L=8in</h2><h2>W=5in</h2>
Step-by-step explanation:
Step one:
given data
we are told that the border/perimeter of the yellow ribbon is 26in
let the width be x
W=x
and the lenght
L=x+3
Step two:
Required
The expression for the perimeter to find the dimensions of the yellow ribbon given the above condition.
we know that the perimeter of a rectangle is given as
P=2L+2W
26=2(x+3)+2x---------This is the expression required
26=2x+6+2x
26=4x+6
26-6=4x
20=4x
divide both sides by 4
x=20/4
x=5in
The width is 5in
The length is
L=x+3
L=5+3
L=8in
