Perimeter of the carpet = 21.8 m

Area of the carpet = [tex]29.4 $ m^{2}[/tex]

Given:

Dimension of the living room:

[tex]l = 4.9 $ m\\w = 6 $ m[/tex]

A. Perimeter of the carpet = perimeter of a rectangle

Perimeter = [tex]2(l + w)[/tex]

Substitute

[tex]Perimeter = 2(4.9 + 6)\\= 21.8 $ m[/tex]

Perimeter of the carpet = 21.8 m (The digits here are significant)

B. Area of the carper = area of a rectangle

Area = [tex]l \times w[/tex]

Substitute

[tex]Area = 4.9 \times 6\\= 29.4 $ m^{2}[/tex]

Area of the carpet = [tex]29.4 $ m^{2}[/tex] (the digits here are significant)

Therefore, considering the rules of significant digits:

Perimeter of the carpet = 21.8 m

Area of the carpet = [tex]29.4 $ m^{2}[/tex]
