Step-by-step explanation:
1. Given,
Side of the cube = 9 cm
Therefore, volume of the cube = side × side × side
= 9cm × 9cm × 9cm
[tex] = 729 {cm}^{3} (ans)[/tex]
2. Given,
Length of the rectangle = 4cm
Breadth of the rectangle = 3cm
Therefore, perimeter of the rectangle = 2(l+b)
= 2(4cm + 3cm) = 2 × 7cm = 14 cm (Ans)
3. Given,
Side of a square = 11 m
Therefore, area of the square = side × side
= 11 m × 11 m
[tex] \: = {121cm}^{2} (ans)[/tex]
4. Given,
Length of the rectangle = 14 m
Width of the rectangle = 5 m
Therefore, area of the rectangle = l × b
= 14 m × 5 m
[tex] = 70 {m}^{2} (ans)[/tex]
5. Given,
Side of the equilateral triangle = 15 cm
Therefore, perimeter of the triangle = 3 × side
= 3 × 15 cm = 45 cm (Ans)
