Question

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

• A. 450 m
• B. 100 m
• C. 900 m
• D. 1250 m

Answer 1

Answer:

A. 450 m

Solution: Given: Area of a rectangular ground (A) = 12500 m2 Length (L) = 125 m Concept used: Area of rectangle = Length × Breadth Perimeter = 2 × (Length + Breadth) Calculation: Area of rectangle = Length × Breadth 12500 = 125 × Breadth ⇒ Breadth = (12500/125) = 100 m Perimeter = 2 × (Length + Breadth) = 2 × (125 + 100) = 450 m ∴ Perimeter of rectangular ground = 450 m
