David wants to build a pen for his goat. He wants the area of the pen be 48 square feet .if the length and width of the pen are whole numbers which of the following could be the perimeter of the pen.
A. P= 26
B. P= 28
C. P= 30
D. P= 36
PLEASE HELP!

Respuesta :

B.

The reason being said Area is l*w

or length*width

Try 8*6=48 sq ft.

But perimeter is the outer edge..

l+l+w+w=P

8+8+6+6=28

Simple.

Thus, B, is your answer.

Alrighty, pretty much, A=bh and P=(b=h)2
If you divide 28 by 6, you are left with 8, making h=6 and b=8
If you plug this in for perimeter, you have 28

The answer is B. P= 28 feet
