Question

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

Answer 1

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.

Answer 2

Answer:

Given :-

• Length of wall = 3m 50cm
• Breadth of wall = 5m
• Height of wall = 3 m

To Find :-

Area of 4 walls

Solution :-

Here,

we will use the formula

$\frak \red{Area \: of \: 4 \: wall = 2h (l + b)}$

H is the height

L is the Length

B is the Breadth

Length = 350/100 = 3.5 m

$\sf \implies Area \: of \: 4 \: wall = 2(3)(3.5 + 5)$

$\sf \implies \: Area \: of \: 4 \: wall = 2(3)(8.5)$

$\sf \implies \: Area \: of \: 4 \: wall = 6(8.5)$

$\frak \pink{Area \: of \: 4 \: wall = 51 \: m {}^{2} }$
