Answer:
30cm
Step-by-step explanation:
area of a Trapezium = 1/2()a+b)h
a and b are the two sides
h is the height
Given
Area = 400 cm^2
a =20cm
h = 16cm
Required
b
Substitute
400 = 1/2(20+b))*16
800 = (20+b)*16
800/16 = 20 + b
50 = 20 + b
b = 50-20
b = 30cm
Hence the length of other side is 30cm

Solution
I'm assuming you want this simplified. If not leave a note.
a(x + 1) - b(x + 1) - x - 1 remove the brackets
ax + a - bx - b - x - 1 gather like terms
ax - bx - x + a - b - 1
x(a - b - 1) + (a - b - 1) Use the distributive property to simplify
Answer
(x + 1)(a - b - 1)
The common factor is (a - b - 1). That can be pulled out on either side of the isolated + sign
