The Side = 5
and Diagonal = 5Root2
However, the question says Diagonal in terms of the area so
D = Root(25*2) = Root 2X
P.s. i fell for the trap too
og ps 77

for me its more of a formula than anything else..simba12123 wrote:if a square region has area x, what is the length of its diagonal in terms of x?
a. root x
b.root 2x
c.2 root x
d. x root 2
e. 2x
qa is b
however when plugging in numbers i cant see why d is wrong?
For a square..
Area = s^2 ( where "S" is the side ) and
diagonal is sqrt 2 * S
thus if the area is X . it means side is rt X
and diagonal is rt 2* rt X
which is
sqrt (2X)..
hence B .. hope that helps..

We can create the following equation:simba12123 wrote:if a square region has area x, what is the length of its diagonal in terms of x?
(A) √x
(B) √(2x)
(C) 2√x
(D) x√2
(E) 2x
side^2 = x
side = √x
To calculate the diagonal of a square, multiply its side by √2.
So, the diagonal = (√x)(√2) = √(2x).
Answer: B
