Question

Work out the value that should go in the box. cm =? area = 18 cm² 6 cm​

Answer 1

3 cm

Explanation:

1. Formula for parallelogram area → A = L(W)

Length = 6

Width = ?

Area = 18

2. Substitution into formula

A = L(W)

18 = 6(?)

3. Solve

18 = 6(?)

Divide both sides by 6

18/6 = 6?/6

3 = ?

4. Solved

Answer = 3cm

Answer 2

3 cm

Explanation:

The area of a parallelogram is found using the formula:

`A = l \cdot w`

We are given the following dimensions:

• 
  `A = 18`
• 
  `l = 6`

If we plug these dimensions in for the variables in the area formula, we can solve for the parallelogram's width:

`18 = 6 \cdot w`

↓ dividing both sides by 6

`3 = w`

↓ swapping the sides

`\boxed{w = 3\text{ cm}}`
