Question

The area of rectangular plot is 2400 square metre and its length is 1 and 1/2 times to it's breadth. What is the perimeter

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

$Perimeter \: the \: plot (P)=200\:m$

Step-by-step explanation:

Dimensions of a Rectangular plot:

Breadth = b m

Length (l)= one and half times of breadth

= 3b/2 m

Area of the rectangular plot (A) = 2400 m² (given)

$l \times b = 2400$

$\implies \frac{3b}{2} \times b = 2400$

$\implies b^{2}= \frac{2400\times 2}{3}$

$\implies b^{2}= 800\times 2$

$\implies b^{2}=1600$

$\implies b = \sqrt{1600}$

$\implies b = 40 \: m$

$Now, l = \frac{3b}{2}\\=\frac{3\times 40}{2}\\=3\times 20\\= 60\: m$

Therefore,

$Perimeter \: the \: plot (P) = 2(l+b)\\=2(60+40)\\=2\times 100\: m \\= 200 \: m$
