Question

find the area of square each of whose sides measures 8.5 m.

Answer 1

hlo friend!!

area of square = a²
given side = 8.5m
so,area of square = 8.5²
                              = 8.5*8.5
                              = 72.25m²

hope it helps u!

Answer 2

We Know That
$area \: of \: square \: = \: {a}^{2}$
SO ACCORDING TO THE FORMULA WE CAN PUT 8.5 IN THE VALUE OF a

THEN ,
$area \: = \: {8.5}^{2}$
Which is
$8.5 \times 8.5 \: = \: 72.25 \: {cm}^{2}$
