Answer:
P = 28 cm
Step-by-step explanation:
The area of a square is
A = s^2 where s is the side length
49 = s^2
Taking the square root of each side
sqrt(49) = sqrt(s^2)
7 =s
Now find the perimeter of the square
P = 4s
P = 4(7)
P = 28 cm
see diagram
we see we doulbe the 3 to add
3*2=6
6+12=18
6+15=21
thelength and width of the surfface is 18 by 21
P=2(L+W)
P=2(21+18)
P=2(39)
P=78
the perimiter is 78ft
