​

Answer 1

Given

• A rectangular swimming pool was 6 m wide with a surface of 90 square metres.

⠀

To find

• Length of the swimming pool.

⠀

Solution

• Here in this question, surface means the area of the swimming pool. In simple words, area of the swimming pool is 90m² (given).

⠀

As we know

⠀

☆ Area = Length × Breadth

⠀

→ Area = 90

⠀

→ Length × Breadth = 90

⠀

→ Length × 6 = 90

⠀

→ Length = 90/6

⠀

→ Length = 15

⠀

Hence,

• Length of the swimming pool is 15m.

⠀

⠀

⠀⠀⠀⠀⠀Some Formulae

⠀

→ Area of square = (side)²

⠀

→ Area of rectangle = length × breadth

⠀

→ Area of triangle = ½ × base × height

⠀

→ Area of parallelogram = base × height

⠀

→ Area of Circle = πr²
