Answer 2

Answer:

d) 189m²

Step-by-Step Explanation:

The ratio of the length and breadth of a plot is 7:3.

Let the rational between length and breadth be x  

Hence, length of the plot is 7x metres and breadth of the plot is 3x metres

We know Perimeter = 2 (length + breadth)

60 = 2 (7x + 3x)

60 = 2 (10x)

20x = 60

x = 60/20

x = 3

The rational is 3

Therefore the length of rectangle 7x = 7 × 3 = 21 metres

the breadth of rectangle 3x = 3 × 3 = 9 metres

We know Area of rectangle = length × breadth

Area of rectangle = 21 m × 9 m

Area of rectangle = 189m²

Answer : the area of rectangle is 189m²
