Question

Jimmys garden has a length 2b+4 and a width of 7b-2. what is the perimeter?

Answer 1

The answer: perimeter = 18b+4

This is because (2b+4) + (2b+4) = 4b+8
And (7b-2) + (7b-2) = 14b-4
Therefore, (4b+8) + (14b-4) = 18b+4

Answer 2

18b + 4

Explanation:

2(2B + 4)

2(7B-2)

4b + 8

14b - 4

18b + 4
