Question

Could someone answer question 5

Answer 1

P = 4s
P = (120)^1/2
4s = sqrt120
s = sqrt120/4

A = 2s
2*sqrt120/4 = sqrt120/2
Number 5 is the square root of 120 divided by 2

Answer 2

P= sqrt120
P = 4s
4s= sqrt 120
4s = 2sqrt 30
s = (sqrt 30)/2
Area = s*s or s^2
A= ((sqrt 30)/2)^2
A= 30/4
A= 7 1/2 cm^2
