how many envelopes can be made out of a sheet of paper 3 m 24 cm by 1 m 72 cm,if each envelope requires a piece of paper of size 18 cm by 12 cm?
Answers
Answer:
length of the paper = 324cm
breadth. = 172cm
area of the rectangle = l x b
apply the values in the formula and find area
the find the area of the envelope
l is 18cm and b is 12cm
area of the envelope = 18 x 12
then divide the area of the sheet of paper by area of the envelope
u will get the answer
or
length of the sheet of paper=3m 24cm(324 cm)
breadth of the sheet of paper=1m 72 cm(172 cm)
area of sheet of paper=l×b
=324cm×172cm²
Area of the piece of paper required for an envelope=18×12cm²
No. of envelopes=324 172=258 envelopes
×
18 12
2.the sheet of paper is
324 cm by 172 cm
The tempation is to say:
area of whole paper = 55728 cm^2
area of 1 envelope = 216
so we have 55728/216 or 258 envelopes.
