Answer 1

$\color{red}\huge{\underline{\underline{GIVEN\dag}}}$

• $length(l )= 20cm$
• $breadth(b) = 12cm$

$\color{red}\huge{\underline{\underline{SOLUTION \dag}}}$

Since the length of 'colored tape' is equal to perimeter of rectangle.

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

$perimeter = 2(20 + 12)$

$perimeter = 2(32)$

$\orange{ \therefore \boxed{perimeter =64cm}}$

Therefore,length of 64cm colored tape is required.
