Question

solve the above question​

Answer 1

Answer:

Dimension of the plot is 150m and 70m

Step-by-step explanation:

There is a narrow rectangular plot, reserved for a school, in a city. the length and breadth of the plot are in the ratio 15 : 7.  

let

the common multiple be x  

So,

the length will be 15 x  

breadth = 7 x

We know that :-

Perimeter = 2( L + B )

put the value of length and breath

=> $p=2(15x+7x)$

=> $p=2(22x)$

=> $p=44x$

At the Rate of 100 Rs per meter

=> 44x × 100

=> 4400x

According to the Question

4400x = 44000

x  = 10

Now,

Length  = 15x = 15 × 10  = 150m

breath = 7x = 7 × 10 = 70m

Answer

Dimension of the plot is 150m and 70m

Answer 2

$\huge \bf\underline\red{Answer}$

Let dimensions be = 15x , 7x

Perimeter = 2( l+b )

⠀⠀⠀⠀⠀⠀ = 2( 15x + 7x)

⠀⠀⠀⠀⠀⠀ = 2( 22x)

⠀⠀⠀⠀⠀⠀ = 44x

1 meter = Rs. 100

Total meter = Rs. 4400

⠀⠀⠀⠀⠀⠀ Perimeter = $</strong><strong>\</strong><strong>s</strong><strong>f</strong><strong> \frac{44000}{100}$

⠀⠀⠀⠀⠀⠀ $</strong><strong>\</strong><strong>s</strong><strong>f</strong><strong> = 440m$

ATQ→

⠀⠀⠀⠀⠀⠀ 44x = 440

⠀⠀⠀⠀⠀⠀ x = 440/44

⠀⠀⠀⠀⠀⠀ x = 10

Length = 15×10 = 150 m

Breadth = 7×10 = 70 m
