Whats the are of this figure?!?

Answer:

The area is 5.5 cm squared.

Step-by-step explanation:

To find the area, you have to find the areas of the rectangle and the triangle separately and then add your two values together.

The formula for the area of a rectangle is as follows:

A=lw

In this formula, "l" refers to length and "w" refers to width.

As shown in the diagram, your length is 1.5 cm and your width is 2 cm.

Simply plug these numbers into the formula and simplify.

A=1.5*2\\A=3

The area of the rectangle is 3 cm squared.

Next, find the area of the triangle. The formula for the area of a triangle is as follows:

A=\frac{1}{2} bh

In this formula, "b" refers to the measure of the base and "h" refers to the measure of the height.

Your base (b) is 2 cm.

To find your height, subtract the length of the rectangle (1.5 cm) from the total length of the shape (4 cm). This will give you a height of 2.5 cm.

Next, plug your values into the formula and simplify.

A=\frac{1}{2} *2*2.5\\A=1*2.5\\A=2.5

The area of the triangle is 2.5 cm squared.

Add the area of the rectangle (3 cm squared) to the area of the triangle (2.5 cm squared), and you have the area of the entire figure (5.5 cm squared).

Note: Carlos' mistake in the problem is that he forgot to subtract the length of the rectangle from the length of the entire shape, and incorrectly used 4 cm as his height for the triangle rather than 2.5 cm.

The population of a town increased from 3450 in 2006 to 4650 in 2011. Find the absolute and relative (percent) increase.
netineya [11]

Answer:

15% increase per year.

Step-by-step explanation:

5,600 - 3,500 = 2,100

2,100 is what percent of 3,500?

2,100 = X*3,500

X =  2,100 / 3,500

X = .60 or 60%

An average of 15% increase per year.

Two lines that have the same slopes, when will they intersect
taurus [48]

Answer: No. If two lines have the same slope they are parallel lines (or they are the same line), so they cannot intersect at one point. Because the triangles are congruent, the angles where the lines meet the x-axis are congruent. Because the lines form the same angle with the x-axis, they are parallel.
