Question

the length of arectangular plot of a land is twice its breadth and it's perimeter is 60 m. the area of rectangle is? ​

Answer 1

Answer:

Area Of The Plot is 200m²

Step-by-step explanation:

$let \: the \: length(l) \: be \: 2x \: and \: \\ breadth(b) \: = \: x \\ = )perimeter \: of \: rectangle \: = 2(l + b) \\ = )2(l + b) = 60 \\ = )2(2x + x) = 60 \\ = )2 \times 3x = 60 \\ = )6x = 60 \\ = )x = 10$

$Length = 2x \\ </p><p>=)2 \times 10</p><p>=)20 m \\ </p><p>Breadth = x \\ </p><p>=)10 m$

Now,

$area \: of \: rectangle \: = length \: \times breadth \\ = )20 \times 10 \\ = )200m$
