blueberrybaby114.02.2022 07:50Step-by-step explanation:

Given,

Perimeter of a rectangular pool (P) = 40 feet

Length of the pool (l) = 12 feet

Let,

Width of the pool be = w

As we know,

Perimeter of a rectangle = 2(length + width)Therefore,

By the problem,

=> 2(l + w) = P

[On substituting the values of l = 12 and P = 40]=> 2(12 + w) = 40

[On multiplying 2 with 12 and w]=> 24 + 2w = 40

[On subtracting both sides with 24]=> 24 - 24 + 2w = 40 - 24

[On Simplifying]=> 2w = 16

[On Dividing both sides with 2]=> =

[On Simplifying]=> w = 8

Hence,

The required width of the pool is 8 feet. (Ans)

micro790914.02.2022 07:50The Width of the pool would be 8 feet/ft. .

Step-by-step explanation:

According to the Question Given:

Perimeter = 40 ft/feet

Length of the pool = 12 ft/feet

To Find:

The width/breadth of the pool

Solution:

We know that,

So Put their values accordingly:

Perimeter of The Rectangle = 40Length[L] = 12We got an equation.By this method we can easily find the breadth/width of the pool.

Solve this equation:

Flip the equation:

Transpose 24 to the RHS[remember to change its sign]:Simplify:Divide both sides by 2:

Use Cancellation method and cancel LHS and RHS:Hence, the breadth/width of the pool would be 8 ft./feet .

I hope this helps!
