Answer :
Let
- width be x
- Length=8x-38
- Area=4050m^2
We know
[tex]\boxed{\sf Area =Length\times Width}[/tex]
[tex]\\ \sf\longmapsto x(8x-38)=4050[/tex]
[tex]\\ \sf\longmapsto 8x^2-38x=4050[/tex]
[tex]\\ \sf\longmapsto 8x^2-38x-4050=0[/tex]
- By solving
[tex]\\ \sf\longmapsto x=\dfrac{81}{4}\:or\:x=25[/tex]
- Take x as 25
[tex]\\ \sf\longmapsto Length=8x-38=8(25)-38=200-38=162m[/tex]
