Question

Find area of four walls of rectangular field when length=3m50cm, breadth=5m, height=3m

Answer 1

Answer:

51 m^2

Step-by-step explanation:

length=l  breadth=b  height=h

Four walls area = 2h(l+b)

                          = 2*3(3.5+5)

                          = 6(8.5)

                          = 51m^2

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.
