Answer 1

i think its b

Answer 2

welcome to open study flower

Answer 3

thank you

Answer 4

Lets take the information 1 sentence at a time ok

Answer 5

Perimeter for a rectangle is:

P = 2*L + 2*W

Answer 6

"The length is 7 units longer than the width"

L = W + 7

Answer 7

i think this answer is b im kinda not sure though

Answer 8

we will get there... you see how i got

L = W + 7
from " the length is 7 units longer than the width?

Answer 9

yes

Answer 10

Perimeter:
P = 2*L + 2*W

Now we are told : L = W + 7, put that into the perimeter above for L

P = 2*(W+7) +2*W

Answer 11

You see how i just replaced the L in the perimeter , with the info they told you , the length L is 7 larger than the width W.

L= W+ 7
