Question

The perimeter of a rectangle is 30 m and the ratio between length and breadth is 7:3. Find the area of the rectangle.

Answer 1

Answer:

Step-by-step explanation:

perimeter = 30 m

2(l+b)= 30 m

2(7x+3x) = 30

10x = 15

x = 10/15

x = 2/3

length = 7x = 7*2/3 = 14/3m

breadth = 3x = 3*2/3 = 6/3 = 2m

area = length*breadth

area = 14/3*2 =28/3m^2

                      = 9.3 meter square approximately
