Question

Sharon has a piece of cloth of area 170 cm^2 ;can she make a square handkerchief of length 12.5 cm?

Answer 1

of the handkerchief :-

each side = 12.5 cm
area = (12.5)^2
= (125/10)^2
=(25/2)^2
= 625/4 cm^2
=156.25 cm^2

we observe that

156.25 <170

therefore she can make the handkerchief.

Answer 2

Hi there !!

Total cloth available = 170 cm²

Side of the square handkerchief = a = 12.5 cm

Area of the handkerchief = a²
        
                                        = (12.5)²
   
                                       = 156.25 cm²

So , the area of handkerchief is less than total cloth available.

156.25 < 170

Hence , Sharon can make the handkerchief
