Question

Q6. The area of a rectangular plot is 616 square metre and its breadth is 22m. Find the length of the plot and the cost of fencing at the rate of Rs 7.50 per metre. *

Length = 28m ,cost of fencing = Rs700

Length = 24m, cost of fencing = Rs450

Length = 28 m ,cost of fencing =Rs 750

​

Answer 1

Answer:

area of rectangular plot = length × breadth

= 616 m² = length × 22m

= 616/22 m = length

length = 28 m

cost of fencing = perimeter × cost

perimeter of rectangular plot × cost

2(l+b) × 7.50

2(28+22) × 7.50

100 × 7.5 = Rs 750

pls mark me as brainliest.....

Answer 2

Given

$\bold{Area \ of \ the \ rectangular \ plot} = 616 m^{2}$

$\bold{Breadth \ of \ the \ rectangular \ plot} = 22m$

SOMETHING YOU NEED TO KNOW

$\bold{Length \times Breadth = Area \ of \ the \ rectangle}$

$\bold{2(Length+Breadth)=Perimeter \ of \ the \ rectangle}$

Let the length of the rectangle be x.

$\implies 22x=616$

$\implies x = \dfrac{616}{22}$

$\implies \underline{\underline{ x = 28 \ m}}$

$\boxed{\boxed{\bold{ Therefore, \ the \ length \ of \ the \ rectangle \ is \ 28 \ m }}}$.

The Perimeter of the rectangle:

$\implies 2(28+22)\\\implies 2 \times 50\\\implies \underline{\underline{ 100m}}$

$\bold{Cost \ for \ fencing} = 7.50 \ Rs.$

Total cost :  $7.50 \times 100$

$= 750 \ Rs$

$\boxed{\boxed{\bold{ Therefore, \ the \ perimeter \ of \ the \ rectangle \ is \ 750 \ m }}}$
