PLS DO #2 I WILL GIVE BRAINLIEST

180 ft²

Step-by-step explanation:

The figure is composed of 2 triangles and a rectangle between them

Calculate area of triangle on left

A = bh ( b is the base and h the perpendicular height ), thus

A = × 9 × 6 = 4.5 × 6 = 27 ft²

Area of rectangle = 12 × 9 = 108 ft²

Calculate the area of the triangle on the right

A = × 9 × 10 = 4.5 × 10 = 45 ft²

area of composite figure = 27 + 108 + 45 = 180 ft²

step-by-step explanation:

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
