The total area of the rectangles are:
a. Area = 15a
b. Area = 2x
c. Area = 3r
d. Area = 24p
e. Area = 14m
f. Area = 15x + 40
<h3>What is the Area of a Rectangle?</h3>
Th area of a rectangle is given by the formula: length × width
a. width = 3
Length = 5 + a = 5a
Area = 5a × 3 = 15a
b. width = 1/3
length = 6x
Area = 6x × 1/3 = 2x
c. width = r
length = 3
Area = 3 × r = 3r
d. width = 6
length = 4p
Area = 4p × 6 = 24p
e. width = m
length = 6 + 8 = 14
Area = 14 × m = 14m
f. width = 5
length = 3x + 8
Area = (3x + 8)5 = 15x + 40

Answer:
Step-by-step explanation:
From B on the ground straight up to A and then turn the corner to follow the dotted line...that is a 90 degree angle. So in order to find the angle of depression, subtract 66 from 90 to get 24 degrees. Subsequently, that is also the angle of elevation (the base angle inside the triangle) due to parallel lines and whatnot.
X1=(-16√16^2-4*1*9)/(2*1) = (-16 - 2*√55)/ 2=-15.416
X2=(-16+√16^2-4*1*9)/(2*1) = (-16+2*√55)/2=-0.584
