(1) 450 m
(2) 100 m
(3) 900 m
(4) 1250 m​

Answer 1

Required Answer :

Option (1) 450 m

Area of rectangular ground is 12500 m². Its length is 125 m its perimeter is 450 m

Given :

• Area of rectanglular ground = 12500 m²
• Length of the rectangular ground = 125 m

To find :

• Perimeter of the rectangular ground

Solution :

Using formula,

• Area of rectangle = l × b

Substituting the given values :

⇒ 12500 = 125 × b

⇒ 12500/125 = b

⇒ 100 = b

Breadth of the rectangular ground = 100 m

Using formula,

• Perimeter of rectangle = 2(l + b)

Substituting the given values :

⇒ Perimeter of rectanglular ground = 2(125 + 100)

⇒ Perimeter of rectanglular ground = 2(225)

⇒ Perimeter of rectanglular ground = 450

Therefore,

• The perimeter of a rectangular ground = 450 m
