Question

The area of a rectangular lawn is 225 m². If its length is 15 m, find its perimeter.​

Answer 1

Answer:

❀given:

Area of Rectangular lawn = 225m²

Length of Rectangle = 15m.

❀ To Find:

Perimeter of Rectangle.

Formulae used:-

Area of rectangle = L × B

Perimeter of Rectangle = 2 ( L + B )

Now,

$↦$Area of Rectanglular = L × B

$↦$ Area of Rectanglular = 15 × x

$↦$225 = 15x

$↦x = \sf{\dfrac{225}{15}}$

$↦$ x = 15

Hence, The Breadth of Rectangle is 15m.

Now,

$↦$ Perimeter of Rectangle = 2 ( L + B)

$↦$ Perimeter of Rectangle = 2 ( 15 + 15 )

$↦$ 2 × 30

$↦$ 60m²

Hence, The Perimeter of Rectangle is 60m².

Given:-

Area of Rectangular lawn = 225m²

Length of Rectangle = 15m.

To Find:-

Perimeter of Rectangle.

Formulae used:-

Area of rectangle = L × B

Perimeter of Rectangle = 2 ( L + B )

Now,

→ Area of Rectanglular = L × B

→ Area of Rectanglular = 15 × x

→ 225 = 15x

→ x = \sf{\dfrac{225}{15}}

15

225

→ x = 15

Hence, The Breadth of Rectangle is 15m.

Now,

→ Perimeter of Rectangle = 2 ( L + B)

→ Perimeter of Rectangle = 2 ( 15 + 15 )

→ 2 × 30

→ 60m²

Hence, The Perimeter of Rectangle is 60m².
