Question

the ratio of the length to the breadth of a rectangle is 7:3 . find its dimensions , given that its perimetre is 60 m . also , find its area​

Answer 1

Answer:

Dimensions = 21m x 9m; Area = 189m²

Step-by-step explanation:

Let the length and breadth be having ratio in the form 7x:3x

Now, given that Perimeter(P) = 60m

P = 2(length + breadth)

60 = 2(7x + 3x)

30 = 10x

x = 3

So, length = 7x = 7 * 3 = 21m

Breadth = 3x = 3 * 3 = 9m

Area of rectangle = length x breadth

Area of the area = 21 * 9 = 189m²
