Step-by-step explanation:

The area of one envelope can be considered to be the sum of the areas of ...

a 14cm x 30 cm triangle: A = (1/2)(14 cm)(30 cm) = 210 cm^2a 32 x 20 rectangle: A = (32 cm)(20 cm) = 640 cm^2a 30 x 20 rectangle: A = (30 cm)(20 cm) = 600 cm^2

for a total of ...

(210 +640 +600) cm^2 = 1450 cm^2

The area of one sheet of paper is ...

A = LW = (130 cm)(220 cm) = 28600 cm^2

The ratio of paper area to envelope area is ...

28600/1450 ≈ 19.7

Considered as a 32 cm by 54 cm rectangle, the area of the envelope is ...

A = (32 cm)(54 cm) = 1728 cm^2

and the ratio of paper area to envelope area is ...

28600/1728 ≈ 16.6

That is, considering space utilization, the best that can be done is to cut 16 envelopes from each sheet of paper.

The supply paper comes in sheets that are 130cm by 220cm. How many envelopes can the company make fr
