Question

A rectangular swimming pool is 30 inches wide and 40 inches in length. Find the total area and perimeter of the swimming pool.​

Answer 1

Let the breadth of rectangular swimming pool be x metres.

Then, its length =(2x+2) metres.

We know that the Perimeter of a rectangle =2(Length+Breadth)

=2(2x+2+x)=6x+4

According to the given condition, we have

6x+4=154

⇒6x=154−4 ..[By transposing 4 to RHS]

⇒6x=150

⇒ x/6 = 150/6

...[Dividing both sides by 6]

⇒x=25

Thus, breadth =25 m and length =25×2+2=52 m

Answer 2

Answer:

The area and the perimeter will be 1200 sq. inches and 140 inches respectively

Step-by-step explanation:

Here the length and breadth of a rectangular swimming pool is given

length = 40 inches

width =  30 inches

We have to find the area and the perimeter

area = length × breadth

       = 40 × 30

      = 1200 sq. inches

perimeter = 2 ( length + width )

               = 2 ( 40 + 30 )

               = 2 × 70

               = 140 inches
