Answer 2

$\large\bf{\underline\blue{Good \: Evening↝}}$

Let length and breadth be 5x and 4x.

Area of triangle = length × breadth

320cm² = 5x × 4x

320 = 20x²

${x}^{2} = \frac{320}{20}$

${x}^{2} = 16$

$x = \sqrt{16}$

$x = 4$

Therefore, the length = 5x = 5(4) = 20cm

and the breadth = 4x = 4(4) = 6cm.
