Question

find the breadth of a rectangular plot of length 45m having perimeter 140m. also find it's area.

Answer 1

Step-by-step explanation:

Let the breadth be x m

Length =45m

Perimeter of rectangle =140m

2(l+b)=140m

45+x=140/2

x=70-45

Breadth =25m

Area of rectangle =l*b

45*25=1125m²

Hope it helps

Answer 2

Step-by-step explanation:

Let:

$\implies$ Length be ' l '

$\implies$ Breadth be ' b '

Perimeter of Rectangular Plot:

$\implies$ 2 × ( l + b )

$\implies$ 140 m

Here, l = 45 m

So:

$\implies$ 2 × ( 45 + b ) = 140 m

$\implies$ 90 + 2b = 140 m

$\implies$ 2b = 50

$\implies$ b = 25 m

Therefore: Breadth is 25 m

And:

Area = Length × Breadth

$\implies$ 45 × 25

$\implies$ $\sf{1125\:m^{2}}$

Final answer: $\sf{1125\:m^{2}}$
