Answer 1

Answer :-

1) Simplify

>>> -343 - 219

= -(343 + 219 )

= -( 562)

= - 563

>>> 28 + (-33)

= 28 - 33

= -(33 - 28)

= -(5)

= 5

2)

Length = 110m

Price = Rs 15 per m

Now

as per meter costs Rs 15

therefore 110 m will. cost

= 15 × 110

= Rs 1650

3)

9m to cm

as 1 m = 100 cm

=> 9 m = 9 × 100

= 900 cm

4) now length of rectangular room = 16 m

= 1600 cm

also length of square tiles = 40 cm

so to cover it's length no of tiles required

= 1600 ÷ 40

= 40

Now breath of rectangular room = 11m

= 1100 cm

also we know that length of tiles = 40 cm

Then no of tiles required = 1100 ÷ 40

= 27.5

Now total tiles required

= 40 × 27.5

= 1100

5) Perimeter = 15 cm + 3cm + 1cm + 1cm + 4 cm + (15 - 2 cm )

= 37 cm

Answer 2

$\textbf{Hello mate!}$

$\textbf{Perimeter}$ = $\textbf{Sum of all sides}$

15 cm + 10 cm + 10 cm + 10 cm + 4 cm + 3 cm = 52 cm

$\textbf{Hope this helps you}$
