Answer 2

Answer:

perimeter of a rectangle is 120cm

the ratio of its length 2x and width 1x

perimeter of rectangle 2( l + b)

2 ( 2x + 1x ) = 120

4x + 2x = 120

6x = 120

x = 20

length = 2(20) = 40

width = 1(20) = 20

According to the question

Area of rectangle equal length X breadth

= 40 × 20

= 800 cm
