Question

The area of a rectangular park is 240 m² and it's breadth is 15m . What is the perimeter of the park​

Answer 1

Area = 240 m²

Breadth = 15 m

Length × Breadth = Area of rectangle

or, Length = Area / Breadth

or, Length = 240 / 15

or, Length = 16 m

Perimeter of rectangle = 2(Length+Breadth)

Perimeter = 2(16 + 15) m

= 2(31) m

= 62 m

The perimeter of the rectangular park is 62 m.

Answer 2

Answer:

62m

Step-by-step explanation:

$\large\underline{\sf{Solution}}$

$\large\underline{\sf{area \: of \: rectangle = l \times b}}$

$\large\underline{\sf{ {240m}^{2} = l \times 15m}}$

$\large\underline{\sf{240 {m}^{2} \div 15m = l }}$

$\large\underline{\sf{16m}}$

Now we have found the length of the rectangle.

Now we will use the formula for perimeter of rectangle.

$\large\underline{\sf{perimeter _{rectangle} = 2(l + b)}}$

$\large\underline{\sf{ \implies2(16m + 15m)}}$

$\large\underline{\sf{ \implies 2 \times 31m}}$

$\large\underline{\sf{ \implies62m}}$
