Step-by-step explanation:

To calculate actual area based on a scale drawing, take each of the original dimensions and multiply them by the scale factor to get the actual dimensions.

Mathematics

Let the length be x

Let the width be 5+6x

ATQ,

$\boxed{ \bf \: perimeter = 2(l + b)}$

$\sf \: 290 = 2(x + 5 + 6x)$

$\sf \: 145 = x + 5 + 6x$

$\sf \: 145 = 7x + 5$

$\sf \: 145 - 5 = 7x$

$\sf \: 140 = 7x$

$\sf \: 20 = x \: or \: x = 20$

Now,

$\tt \: length = x \\ \tt \: = 20 \: yards$

$\tt \: width = 5 + 6x \\ \tt \: = 5 + 6 \times 20 \\ \tt \: = 5 + 120 \\ \tt \: = 125 \: yards$
