Find the area <br> Please someone help

IgorLugansk [536]

So first let’s find the area of the rectangle. The formula for finding the area of a rectangle is A=l x w.
The length is 10ft and the width is 8ft.
A=10ft x 8ft=80ft^2
The area of the rectangle is 80ft^2.

Now let’s find the area of the triangle. The formula for finding the area of a triangle is A=h x b/2. Both the height and the base of the triangle is 4ft.
A=4ft x 4ft/2=8ft^2.
The area of the triangle is 8ft^2.

Now to find the area of the entire shape. Add the area of the rectangle and the area of the triangle.
80ft^2+8ft^2=88ft^2
The total area of the shape is 88ft^2.

A length of ribbon is cut into two pieces to use in a craft project. The graph shows the length of the second piece, x, for each

djyliett [7]

Answer:

Part A) The length of the ribbon is 15 feet

Part B) $m=-1$

Part C) see the explanation

Step-by-step explanation:

Part A)

Let

x -----> the length of the second piece of ribbon in feet

y -----> the length of the first piece of ribbon in feet

we know that

The length of the ribbon is equal to the sum of the first piece and the second piece of ribbon

so

y+x

take any point from the graph

Example

(13,2)

That means

Second piece ----> x=13 ft

First piece ----> y=2 ft

The length is (y+x)=2+13=15 ft

Part B) What is the slope of the line?

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

take the intercepts from the graph to calculate the slope

we have

(0,15) and (15,0)

substitute

$m=\frac{0-15}{15-0}$

$m=-1$

Part C) Explain what the slope of the line represents

we know that

The slope is equal to -1

That means, that we have a decreasing function, as the value of x (length of second piece) increases by one, the value of y (length of the first piece) decreases by one

The slope fits in the story because the linear equation in slope intercept form between the variable x and the variable y is equal to

$y=-x+15$
