Question

Write an expression for the area of the shaded section

of this rectangle. Expand your brackets.
p+10
6
7

Answer 1

area of shaded section = 6p + 18

Explanation:

the area of the shaded section is calculated as

area of whole rectangle - area of white rectangle

area of whole rectangle = length × width

length = p + 10 and width = 6

area = 6(p + 10 ) = 6p + 60

-------------------------------------------------------

area of white rectangle = length × width

length = 7 and width = 6

area = 7 × 6 = 42

--------------------------------------------------------

area of shaded section = 6p + 60 - 42 = 6p + 18
