A= 27/8 feet

B= 21/4 feet

Step-by-step explanation:

First, on both we need to convert to common denominators:

A.

Multiply:

4 1/4 times 2= 4 2/8

now we have to make 4 2/8 an improper fraction:

4 times 8=32, 32+2=34

34/8

Subtract the below ground length from the total length:

34/8-7/8= 27/8

Repeat:

B.

Multiply:

1 1/2 times 2= 1 2/4

Now we have to make 1 2/4 and 6 3/4 improper fractions:

1 times 4=4+2=6

6/4

6 times 4-24+3=27

27/4

Subtract the below ground length from the total length:

27/4-6/4= 21/4

i hope this helps u pls give a brainliest and a thx ;)
