Answer 1

Hey Buddy the answer is as follows

First we need to find the area of rectangle and then we can find the length of the tape

Therefore, Area of Rectangle= Length × Breadth

= 40cm×10cm

=400cm²

Therefore, taking square root it becomes

√400= 20cm

Therefore, the length of required tape is 20cm

Hope it helps you

Answer 2

Answer : 100 cm

As the question mentions " all around with tape ",,, the lid was sealed along the border,,, Where we have to find perimeter

☆GIVEN

Length of the lid = 40 cm

Width of the lid = 10 cm

☆TO FIND

Length of the tape required to seal along the border ⇨ perimeter of lid itself

☆CALCULATION

As the lid is rectangular in shape,

Formula to find the perimeter of Rectangle :-

⇨ ( l + b ) × 2

= ( 40 + 10 ) × 2

= 50 × 2

= 100 cm
