Question

Given: P = 56 feet, DC = 16 feet, what is the length of BC?

Answer 1

12 feet

Explanation:

this is a rectangle! because DC = 16 feet, you know that AB is also equal to 16 feet

therefore, DA + CB = 24

because ABCD is a rectangle, you know that DA = CB and you can use substitution to say that CB + CB = 24

2CB = 24

CB = 12
