Question

The area of a square garden is 128m squae. How long is the diagonal?

Answer 1

Find the square root first. Then use the pythagorean theorum to find the diagonal.

Answer 2

128=S^2
\[s=\sqrt{128}\]

Answer 3

\[D^2=\sqrt{128}^2+\sqrt{128}^2\]

Answer 4

\[D=\sqrt{256}\]

Answer 5

D=16

Answer 6

\[Area=a^2\]
\[a^2=128\]
\[a=8\sqrt{2}\]

diagonal of square \[= a \sqrt 2 = 8 \sqrt{2\times2}=16\]
