ABCD is a rectangle. Rectangle A B C D is shown. All angles are right angles. The length of A D is 5 and the length of D C is 12.

Use the diagram to answer the questions.

The length of AB is
.

The length of BC is
.

The length of AC is
.

AB = 12    BC = 5   AC = 13

Step-by-step explanation:

opposite sides of a rectangle are congruent, therefore AB = DC = 12

and BC = AD = 5.

Now, AC is found by using the Pythagorean theorem.  

So, = +

            =

            = 144 + 25 = 169

AC = = 13

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
