Answer 2

Answer:-

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

Given:-

Dimensions of the rectangular field are:-

Length = 5 m

Breadth = 4m

Height = 3 m

Let:-

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

We know:-

Area of four walls of rectangle = 2(lb + bh + hl)

Therefore:-

Area of four walls of the given rectangle = 2(3*4 + 4*5 + 5*3)

Area of four walls of the given rectangle = 2(12 + 20 + 15)

Area of four walls of the given rectangle = 2(47)

Area of four walls of the given rectangle = = 94

Hence:-

Area of four walls of the given rectangle is 94 m².
