Question

Devika has a square piece of cloth of area 9 m2 and she wants to make 16 square shaped scarves of equal size out of it. What should possibly be the length of the scarf that can be made out of the piece

Answer 1

let lenght of each piece be x
convert 9m^2 in cm^2
i.e. 90000 cm^2
now 16=90000÷x^2
x^2=90000÷16
x=300÷4
x=75cm
75cm =0.75 m
0.75m is your answer

Answer 2

Answer:

0.75 m should be the length of the scarf that can be made.

Given: The length of the cloth available = $9 \mathrm{m}^{2}$

The number of square shaped scarves required to make from the given length of cloth available = 16

Area of each scarf =  $\bold{\frac{\text {Length of the cloth available}}{\text {Number of square shaped scarves}}}=\frac{9}{16}=0.5625 \mathrm{m}^{2}$

Length of each scarf to be made becomes = √0.5625 = 0.75 m

Hence 0.75 m of 16 scarves can be made from the given  $9 \mathrm{m}^{2}$ length of cloth available.
