Question

Janet was cutting out some fabric for a friend. The piece she cut was 300cm long and had a perimeter of 1500 cm. What was the width of the piece of fabric (in cm)?

Answer 1

Answer:

The width of the piece of fabric was 450 cm

Step-by-step explanation:

Let the width of the cloth was W

If the length is L then the perimeter is given by

$P=2(L+W)$

Here given that

$L=300$ cm

and $P=1500$ cm

Therefore,

$1500=2(300+W)$

$\implies 300+W=\frac{1500}{2}$

$\implies 300+W=750$

$\implies W=750-300$

$\implies W=450$ cm

Therefore, the width of the piece of fabric was 450 cm

Hope this helps.
