<h3>
Answer: 297 square cm</h3>
=============================================
Work Shown:
Break up the figure as shown in the diagram below.
A rectangle and trapezoid form
-------------
Area of rectangle = base*height = 9*15 = 135 cm^2
Area of trapezoid = (1/2)*(b1+b2)*h = (1/2)*(18+9)*12 = 162 cm^2
total area = (area of rectangle)+(area of trapezoid)
total area = (135) + (162)
total area = 297 square cm
Line AB is a line, for the line continues through the points given and goes on 'forever'
hope this helps
If these are the missing parts:
What is the quadrilateral?
a.rhombus
b. rectangle
c. trapezoid
<span>d. square
The quadrilateral formed by the </span><span>two equilateral triangles taped together is A. RHOMBUS.
Rhombus has equal sides but its is different from a square because it looks like a diamond.
Rhombus also have parallel opposite sides and equal opposite angles. </span>
First we take the two points (-7,5) and (-5,9).
Compute the slope:

Then the linear relation may be in the following form

Since the point (-7,5) is on the line, then

The relation is then

.
We check that the other point are on the above line:

W
e have then a linear relation.
The n-th term is given by

Then we can find the common ratio from the given terms.

The appropriate choice is -1.
