Question

The area of a rectangle is 1.7 square units. The length is 3.4 units and the width is z units.

What is the value of z?

z=0.5
z=2
z=5.1
z=5.78

Answer 1

rectangle
A = L * W
1.7 = 3.4 * z
z = 1.7 / 3.4
z = 0.5

answer
z=0.5

Answer 2

`z=0.5`

Explanation:

Given: The area of a rectangle is 1.7 square units. The length is 3.4 units and the width is z units.

To find: Value of z

Solution: We know that area of a rectangle is calculated by multiplying length and width.

Here, length is given by 3.4 units and width is given by z units.

So, area of rectangle is
`3.4* z`

Now, area of the rectangle is given as 1.7 square units.

In order o get the value of z we need to equate the two areas.

`3.4* z=1.7`

`z=(1.7)/(3.4)`

`z=(17)/(34)`

`z=(1)/(2)`

`z=0.5`

Hence,
`z=0.5` is correct.
