Answer 2

Answer:-

• Area of four walls of the given rectangle is 24 m².

Given:-

Dimensions of the rectangular field are:-

• Length = 3m 50 cm = 3.5 m

• Breadth = 5m

• Height = 3 m

Let:-

The length ,breath and height be l, b and h respectively.

We know:-

Area of four walls of rectangle = 2h (l + b)

Therefore:-

Area of four walls of the given rectangle = 2×3(3.5 + 5)

Area of four walls of the given rectangle = 6 × 4= 24 m².

Hence:-

Area of four walls of the given rectangle is 24 m².
