Question

A rectangular piece of land has an area of 3/4 square mile. The land is 21/2 mile. What is its width

Answer 1

The width of the rectangle is
`(1)/(14)` miles

Explanation:

Given as for rectangle

The area of rectangle = A =
`(3)/(4)` mile²

The Length of rectangle = L =
`(21)/(2)` mile

Let The width of rectangle = W miles

Now, From area of rectangle

I.e Area of Rectangle = Length × Width

Or , A =
`(21)/(2)` mile × W mile

Or,
`(3)/(4)` mile² =
`(21)/(2)` mile × W mile

or, W =
`((3)/(4))/((21)/(2))` mile

or, W =
`(3* 2)/(4* 21)`

∴ W =
`(1)/(14)` miles

Hence The width of the rectangle is
`(1)/(14)` miles Answer
