Question

(i) The length of a rectangular field is twice its breadth. Its perimeter is 402 meters. Find its length and breadth.

Answer 1

Answer:

The length is 134 cm and breadth is 67 cm .

Step-by-step explanation:

Given -

The length of a rectangular field is twice its breadth.

Perimeter of rectangle is 402 meters.

To find -

The length and breadth

Solution -

As we know that,

Perimeter of rectangle = $2L+2W$

Where,

L - Length

W - Width

Let , the Breath of a rectangular field is $x$

So, Length of a rectangular field $2x$

put these value in the formula we get

$402 = 2\times 2x +2 \times x$

$402 = 4x +2x$

$402 = 6x$

Divide both side by 6 we get

$x = 67$

So,

Breath of a rectangular field is $x$ = $67\:cm$

Length of a rectangular field $2x$ = $2 \times 67 = 134\:cm$

∴ The length is 134 cm and breadth is 67 cm .
