The length and the breadth of rectangular field are in the ratio of 8 : 7. If charges of the painting the boundary of rectangle is at Rs. 10 per meter is Rs. 3000. What is the area of rectangular plot?

Correct Answer: 5600 sq.m

Explanation:

Perimeter of the rectangle is given by 3000/10 = 300 mts


But we know,


The Perimeter of the rectangle = 2(l + b)


Now,


2(8x + 7x) = 300


30x = 300


x = 10


Required, Area of rectangle = 8x x 7x = 56 x 100 = 5600 sq. mts.
