Question

Alex wants to put a fence around a square garden. The garden has and area of 784 ft2. What is the perimeter of the garden?

Answer 1

Formula for area of square is l^2, where l is the length. Meaning A=l^2
replacing the area and find l, what do you get?

Answer 2

I got 112

Answer 3

No.
the formula is 784=l^2, is not it?

Answer 4

Depends on the shape you are talking about... If its a square,
perimeter = 4*√(s) where 's' is the area.
If its a rectangle,
perimeter = 2*(xy/y + xy/x), 'xy' is their area, 'x' and 'y' are sides. I know this is vague, but the only way you could get it...
If its a circle,
perimeter = 2/r * a where 'a' is the area.
for an equilateral triangle,
perimeter = 3*(√s * √4/ª√3), where 's' is the area, and a=4.

Answer 5

making L subject of the formula, what do you get?

Answer 6

@lisa2005 ?

Answer 7

Answer 8

Okay. I am going to give you the steps on how to make l the subject in the equation of area. Follow this:\[A=l ^{2}\]\[\sqrt{A}=l\]. Clear?

Answer 9

28*4
