Answer:
Area = 152ft²
Step-by-step explanation:
Simpifly:
A = 13(13-6) + 9(13-6)
A = 13(7) + 9(7)
A = 22(7)
A = 22(7)
A = 20(7)+2(7)
A = 140 + 14
A = 152

Answer:
To solve for x, I would use Cosine.
This is because cosine holds the ratio of adjacent/hypotenuse. Based on the diagram, we can see that HYPOTENUSE = x, so we are solving for x. We know the angle, is 17 degrees. Lastly, we know the triangle leg ADJACENT to the angle is 10 units long. So we would use cosine, implementing the ratio adjacent/hypotenuse. Solving this, we would use cos(17)=10/x. Then our goal is to isolate x, so cos(17)=10/x becomes cos(17)*x=10, we are still trying to isolate x, so, x=10/cos(17). Therefore, our answer x = 10.457 units. cosine would be the best way to go.

Let x and y be the dimension of the rectangle. Suppose x is the width and y is the length. Since the perimeter is 36, we have
If we increase the length by 1, we change . Similarly, if the width is increased by 2, we change . So, the increased area is
If we substitute the value for y deduced in the first equation, we have
The solutions to this equation are
One of them is negative, so we have to choose the positive one:
Which implies
