Answer 2

Given:

• Sides of rectangle are in ratio= 4:5
• Perimeter =180cm

━━━━━━━━━━━━━━━━━

Need to Find:

• Measure of sides=?

━━━━━━━━━━━━━━━━━

Now let the sides be:

• 4x and
• 5x

We know perimeter of a rectangle:

2×(length+breadth)

==> 2× (4x+5x) = 180cm

==> 2× 9x= 180cm

==> 18x= 180cm

==> $\blue{x=10cm}$

━━━━━━━━━━━━━━━━

Now

☆ 4x

=4× 10cm

$\red{\bold{=40cm}}$

and

☆ 5x

=5× 10cm

$\red{\bold{=50cm}}$
