Question

area is 128m.sq. in square find the area of diagonal

Answer 1

area of diagonal is= 1/2 area of square
= 1/2*128
=64 m^2

Answer 2

area of square =128

Area of square =side×side
128=(side)square
side =
$8 \sqrt{2}$
then the area of diagonal =1/2×(diagonal)square


dear we use the pythagorous theorem to find the length of the diagonal=16

then we use formula of diagonal =1/2×(diagonal)square
=1/2×16×16
=128m2
