Area of bigger envelope is 50cm * 80 cm= 4000cm^2

Area of small envelope is 10cm* 6cm= 60cm^2

So number of envelopes= Area of bigger envelope/ area of small envelope

                                  = 4000/60= 66.6 = 66 (approx)

Rashmi Bajpayee 8 years, 11 months ago

No. of envelopes = Area of bigger envelope/Area of smaller envelope

                               = 50 x 80 / 10 x 6

                               = 66 (appox.)
