Question

Find the length of the diagonal of a rectangular football pitch with sides 46.9 m and 78.2 m. Give your answer rounded to 1 DP.

Answer 1

Answer:

91.2 m

Step-by-step explanation:

Using Pythagoras theorem:

$a^{2}+b^{2} =c^{2}$

$46.9^{2} + 78.2^{2} = x^{2} \\2199.61 + 6115.24 = x^{2}\\ 8314.85 = x^{2} \\x = \sqrt{8314.85} \\x=91.2m$
