Answer:
324.5m^2
Step-by-step explanation:
To find the area of the composite shape, divide the shape into 3 known shapes and calculate their areas.
SO, here we divide the shape into 2 triangles and 1 rectangle.
Area of rectangle = 15 x 8 = 120m^2
Area of triangle 1 = 1/2 x 7 x 15 = 52.5m^2
Area of triangle 2 = 1/2 x 9 x 8 = 4 x 9 = 32cm^2
Now, the sum of these areas = area of composite shape = 32 + 52.5 + 120 = 204.5m^2
Hope this helps.

Answer:
a) Use the two points to compute the slope, then put that and one of the points into the point-slope form
b) Eliminate parentheses and solve for y to get the equation in slope-intercept form
c) From slope-intercept form, subtract the x-term, then multiply by a common denominator of there are any fractions. Multiply by -1 if necessary to make the x-coefficient positive.
Step-by-step explanation:
a) The slope (m) is computed from two points by ...
... m = (y2 -y1)/(x2 -x1)
That value and one of the points goes into the point-slope form ...
... y -y1 = m(x -x1)
b) Putting the above equation into slope-intercept form is a matter of consolidating all of the constants.
... y = mx +(-m·x1 +y1)
c) Rearranging to standard form puts the x- and y-terms on the same side of the equal sign, preferably with mutually prime integer coefficients. This may require that the equation be multiplied by an appropriate number. The x-coefficient should be positive.
<u>Example:</u>
y -3 = 1/2(x +7) . . . . . . line with slope 1/2 through (-7, 3)
-1/2x + y = 7/2 + 3
x -2y = -13 . . . . . . . . . multiply by -2 to get standard form
