Question

in order to make a shirt 2m 25 cm cloth I'd needed what length of cloth is required to make 18 such shirts?

Answer 1

length of one shirt =2m25cm
=200cm+25cm
=225cm
Length of 18shirts=18*225
=4050cm

Answer 2

40 m 50 cm cloth is required to make 18 shirts.

Step-by-step explanation:

According to the question,

Cloth needed to make one shirt = 2 m 25 cm

First, we shall convert the given value into cm, so as to make the multiplication in the steps ahead a bit easier.

as 1 m = 100 cm

$2 \ m\ 25 \ cm = (2 \times 100 + 25) \ cm = 200+25 \ cm =225 \ cm$

So, cloth needed to make one shirt = 225 cm

Therefore,

Cloth needed to make 18 shirts = $225 \times 18$ cm [Using unitary method]

                                                     = 4050 cm

                                                     = $\frac{4050}{100}$ m          [As 1 m =100 cm]

                                                     = 40 m 50 cm

40 m 50 cm of cloth is needed to make 18 shirts.
