Arectangular piece of land has an area of 3/4 square mile. the land is 21/2 mile. what is its width

The width of the rectangle is   miles

Step-by-step explanation:

Given as for rectangle

The area of rectangle = A = mile²

The Length of rectangle = L = mile

Let The width of rectangle = W miles

Now, From area of rectangle

I.e Area of Rectangle = Length × Width

Or , A = mile  × W mile

Or, mile² = mile  × W mile

or, W = mile

or, W =

∴  W = miles

Hence The width of the rectangle is   miles  Answer

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
