Question

A rectangular path length of 90 cm and 6 m wide a second big square side of 25 cm find the number of square u
sed to make the path

Answer 1

Length = 90 cm

breadth = 6 m = 6×100 = 600 cm

Area of rectangle = length × breadth

=90×600

=54000 cm^2

Area of square = Side^2

= 25×25

=625 cm^2

no. of square required to make the path

= 54000/625

=86 squares

Answer 2

length is in cm.

and wide is in m.

so, first we can convert m into cm,

$6m \times 100cm = 600cm \\ therefore \: the \: area \: of \: rectangle \: = l \times b \\ 90 \times 600 = 54000cm \\ \\ now \: the \: area \: of \: square \: = {s}^{2} \\ ={25}^{2} = 625cm \\ \\ now \: the \: number \: of \: square \: you \: sed \: to \: make \: the \: path \\ \: = \frac{54000}{625} = 86.4$
