To find the total area of this figure, it would be easiest to find the area of the left part (rectangle) and then find the area of the right part (triangle), and then add the two area values together.
First, we will find the area of the rectangle, using the formula A = lw, where l is the length of the rectangle and w is the width of the rectangle.
The length of the rectangle is 13 cm and the width is 9 cm. If we substitute in these values into our equation, we get:
A = (13cm)(9cm)
A= 117 cm^2
Next, let’s find the area of the triangle, using the formula A=(1/2)bh, where b is the base of the triangle and h is the height.
The base of the triangle is 11 cm and the height of the triangle is 5 cm (found by subtracting 13-8 as seen in the figure). If we substitute in these values and simplify, we get:
A=1/2(11cm)(5cm)
A=1/2(55cm^2)
A=27.5 cm^2.
When we add together the area of the rectangle with the area of the triangle, we will get the total area of the figure.
117 cm^2 + 27.5 cm^2 = 144.5 cm^2
Your answer is 144.5 cm^2 or the first option.
Hope this helps!

Yes having a dog is a huge thing if that’s the question you have to provide for the dog make sure the dog doesn’t die of hunger or thirst. Also we have to make sure the dog has no fleas and make sure they are washed.
I would say C: "I don't like it when you do that." because this clearly conveys the teacher's dislike with the student's behavior without berating them. A: "Stop being bad!" may have the opposite effect on a child and they may continue doing it just to irk the teacher further. B: "Now look what you've done!" may give the child a sense of accomplishment at making the teacher angry. <span>D: "Sometimes you're terrible." berates the child and insults them rudely. They may continue doing bad things just to infuriate the teacher as a result of that mean comment.</span>
A) w + 7 = L
B) w * L = 120
A) w = L -7 then substituting this into B)
(L-7) * L = 120
L² -7L = 120
L² -7L -120 = 0
Solving by quadratic Formula:
L1 = 15
L2 = -8
If length = 15, then width = 8
