Question

How many dusters, each 16cm square can be cut from material 84cm long, 36cm wide? What area remains over?

Answer 1

Answer:

11 dusters can be cut and 208$cm^{2}$ is remaining

Step-by-step explanation:

let the area of material be=$l*b$

$=84cm*36cm\\=84*36cm^2$

area of each duster=$a^2$

$16cm*16cm\\=16*16cm^2$

Total amount of dusters

$=84*36cm^2/16*16cm^2\\=11$

Total area covered by dusters=16*16*11

=$2816cm^2$

Total area of material

$84*36\\=3024cm^2$

Remaining Area

$3024 - 2816\\=208cm^2$
