Question

A square has side lengths, s, and a diagonal, d. Complete the equations to answer the questions below.

Answer 1

Hi there!

${s}^{2} + {s}^{2} = {d}^{2}$
According to the Pythagorean Theorem,
${a}^{2} + {b}^{2} = {c}^{2}$
so this statement is true.


Since
${s}^{2} + {s}^{2} = {d}^{2}$
and s = 7, then
${7}^{2} + {7}^{2} = {c}^{2}$
simply:

49 + 49 = c^2
98 = c^2
c = sqrt (98)

Hope this helps!
