1. Find the volume of a cube with a side of 9 cm. 2. Find the perimeter of a rectangle whose length is 4
cm and breadth is 3 cm.
3. Find the area of a square of side 11 m.
4. Find the area of a rectangle that is 14 m long and 5
m wide.
5. Find the perimeter of an equilateral triangle with
side 15 cm.
I'm in tension right now I am studying for exams and I'm tired it would be nice if you help me out!

Step-by-step explanation:

1. Given,

Side of the cube = 9 cm

Therefore, volume of the cube = side × side × side

= 9cm × 9cm × 9cm

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

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

5. Given,

Side of the equilateral triangle = 15 cm

Therefore, perimeter of the triangle = 3 × side

= 3 × 15 cm = 45 cm (Ans)

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300
