Question

if perimeter of rectangle is 500m and it's length is 125 m then find its area​

Answer 1

Answer:

Step-by-step explanation:

Let l and b are length and breadth of rectangle.

Given, l=125m

The perimeter of rectangle=2(l+w)=500

=>2(125+w)=500

=>125+w=500/2

=>125+w=250

=>w=250-125=125

Area of rectange=lw=125*125=15625 m^2

$\green{\underline \bold{Given :}}$

$\:\:$

• Perimeter of rectangle is 500m

• Length of rectangle is 125m

$\:\:$

$\red{\underline \bold{To \: Find:}}$

$\:\:$

• Area of rectangle

$\large{\orange{\underline{\tt{Solution :-}}}}$

$\:\:$

Let the breadth be 'b'

$\:\:$

$\underline{\bold{\texttt{We know that,}}}$

$\:\:$

$\purple\longrightarrow$ Perimeter of rectangle = 2(Length + Breadth)

$\:\:$

$\purple{\underline \bold{According \: to \: the \ question :}}$

$\:\:$

$\sf \dashrightarrow 500 = 2(125 + b)$

$\:\:$

$\sf \longmapsto 250 = 125 + b$

$\:\:$

$\bf\longmapsto b = 125$

$\:\:$

$\underline{\bold{\texttt{We know that }}}$

$\:\:$

$\purple\longrightarrow$ Area of rectangle = Length × Breadth

$\:\:$

$\sf \longmapsto Area \: = \: 125 \: \times\: 125$

$\:\:$

$\bf \dashrightarrow Area \: = \: 15625\: sq \: m$
