Question

Find the diagonal of a square whose area is 64 m
​

Answer 1

Answer:

$4\sqrt{2}$ m =4.5656 m

Step-by-step explanation:

diagonal of a a sqaue is =2$\sqrt{s}$

s= side,side =$\sqrt{area}$=$\sqrt{64 }$=8

diagonal=$2\sqrt{8}$=$2\sqrt{4*2}$=$2\sqrt{2^{2}*2 }$=$2*2\sqrt{2}$=$4\sqrt{2}$=4*1.414=4.5656 m
