Question

nandini's mother has a square piece of cloth of area 1638cm^2. she want to know whether she can make a square bed sheet of side 35 cm. if that is not possible, she want to what is the maximum length of the side of a square bed sheet that she can make from this piece with the minimal wastage

Answer 1

Your Answer

Area of cloth = 1638 cm^2 .
We know ,
Area of square = Side * Side 
She wants to make bedsheet of 35 cm .
then required area = 35*35
=1225 cm^2 .

then ,
 she can make a bedsheet of 40 cm maximum because 
Area = 40 * 40 
= 1600 cm^2 
because 41 cm sheet cannot be made as the cloth area is not enough for it 
because Area = 41 * 41 = 1681 cm^2

Answer 2

If she want to make a Square bed sheet of 35 cm, So area of bed sheet must be equal or lesser than the area of square piece, i.e. 1638 cm^2


Checking, area of bed sheet =35×35
Area of bed sheet = 1225 cm^2


Hence, she can make the square bed sheet of 35 cm





Area of square piece = 1638 cm^2
side = √1638 cm^2
side = 40.47 cm




Hence, the maximum length of square bed sheet can be 40.47 cm
