Text Solution

Verified by Experts

Length of one sheet of aluminium `=43 (3)/(4) ( metre )`
Length of the sheet needed to make one door `=1 (3)/(4)` metre
Number of doors measuring `1 (3)/(4)` metre length can.be made using, this sheet
`=43 (3)/(4)+1 (3)/(4)=(175)/(4) div (7)/(4)=(175)/(4) xx (4)/(7)=25`
