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
