Question

a new rectangular park is planned.it will be 3/4 kilometer long and have an area of 3/8 square kilometers. how many kilometers we will walk the park be ?

Answer 1

The word usage in last sentence of the question is not well presented. However, I can understand that you intend to solve for the width of the park

Answer:

`Width = 2\ km`

Explanation:

Given

`Length = (3)/(8)km`

`Area = (3)/(4)km^2`

Required

Determine the Width

For a rectangle:

`Area = Length * Width`

Substitute for Area and Length

`(3)/(4) = (3)/(8) * Width`

Multiply both sides by
`(8)/(3)`

`(8)/(3) * (3)/(4) = (3)/(8) * (8)/(3)* Width`

`(8)/(3) * (3)/(4) = Width`

`(24)/(12) = Width`

`2 = Width`

`Width = 2\ km`
