• Area of rectangle is 40m²
• Breadth is 5m

Let length be l

$\\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \implies \sf \: area \: of \: rectangle = length \times breadth$

$\\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \implies \sf l \times 5 = 40 {m}^{2}$

$\\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \implies \sf \: l = \frac{40}{5}$

$\\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \implies \sf \: l = 9m$

$\sf \underline{ \pink{ \therefore \: the \: length \: of \: rectangle \: is \: 9m}}$
