Question

the bredth of the rectangular field is twice its length, if the man go 5 rounds around the field ans covers 3000 km, what is the area of the field ​

Answer 1

Answer:

$perimeter \: = 2(l \: \times \: b) \\ \frac{3000}{5} \: = \: 2 ( \: l \: \times \: 2l) \: \: \: \: \: \: \: \: \: \: \: (since \: l \: = 2b) \\ \: \: 600 \: \: = 2(2 {l}^{3} ) \\ \: \: 600 \: \: = 4 {l}^{3} \\ \: \: 150 \: \: = {l}^{3} \\ \sqrt[3]{150}= calculate \: it \: your \: self \: and \: that \: is \: the \: answer.$
