Question

The lengths of average length ofa piece of wire? aaeof2 tubes is 32, if the Istnumber is 40 then what will badhaai 5.50. Find his ffour pieces of wire are 8 m /0 cm, 12 m 25 cm, I8m38 cm and 21 m47 cm. What is the average length of piece of wire .​

Answer 1

perimeter of rectangle frame = 2(l+b)

40=2(l+b)

20=(l+b)

Thus, we have evaluated that the sum of length and breadth is 20.

20 can be written as,

20=19+1 20=14+6

20=18+2 20=13+7

20=17+3 20=12+8

20=16+4 20=11+9

20=15+5

∴Possible measurements of length and breadth are (19cm,1cm), (18cm,2cm), (17cm,3cm)

(16cm,4cm), (15cm,5cm), (14cm,6cm), (13cm,7cm), (12cm,8cm), (11cm,9cm)
