Alex777 [14]

There are 5 little lines between 0 and -1, so each line represents 1/5.

B is located 3 lines to the left of -1, so it would be located at - 1 3/5.

Am absolute value is a positive number so - 1 3/5 would become 1 3/5.

The answer would be A. 1 3/5

The surface area of the three-dimensional figure is square centimeters?

Zina [86]

Answer:

Step-by-step explanation:

Alright, lets get started.

The surface area of the figure given is : The area of all shapes together

The figure has 2 similar triangles and 3 similar rectangles.

The area of 1 triangle =

$\frac{1}{2}*base*height$

The area of 1 triangle = $\frac{1}{2}*10*8.66=43.3$

So, the area of both triangles = $43.3*2=86.6$

The area of 1 rectangle = $width *length$

The of 1 rectangle = $10*15=150$

So, the area of all 3 rectangles = $3*150=450$

So, total area of figure = $86.6+450=536.6$

hence the surface area is 536.6 square centimeters : Answer

Hope it will help :)
