Answer:
10 sqrt(269) = c
164.0121947 = c
Step-by-step explanation:
The diagonal is the hypotenuse of the right triangle
The length and width are the legs of the right triangle
We can use the Pythagorean theorem
a^2 + b^2 =c^2
100^2 + 130^2 = c^2
10000+16900 = c^2
26900 = c^2
Take the square root of each side
sqrt(26900) = sqrt(c^2)
sqrt( 269) sqrt(100) = c
10 sqrt(269) = c
164.0121947 = c
