Question

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

Answer 1

Answer:

let's breadth consider m

area = length×breadth

225m^2 = 15×m

m=225/15

m=15

m as breadth. = 15

Answer 2

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.

• Area of Square = Length × Breadth

• Perimeter of Square = 4 × Side

• Area of Rhombus = Product of Diagonal /2.

• Area of Parallelogram = Base × Height.
