Answer 2

Answer:

The area of the rectangle is 1800 sq.cm.

Step-by-step explanation:

The formula of the perimeter of a rectangle is: $P=2(l+b)$

Given:

P = 180 cm

l = 2b

Compute the value of length and breadth as follows:

$P=2(l+b)\\180=2\times(2b+b)\\180=2\times 3b\\6b=180\\b=30$

The value of l is:

$l=2b=2\times30=60$

Compute the area of the rectangle as follows:

$Area=l\times b=60\times30=1800$

Thus, the area of the rectangle is 1800 sq.cm.
