Question

the area of an square field is 5184 m square ,a rectanglular field whose length is twice its breadth has its perimeter equal to the perimeter of the square field .find the area of the rectangular field

Answer 1

Answer:

4608 sq.m

Step-by-step explanation:

Area of square = (side)^2

Each side = Square root of area =  72 m

Perimeter of square = 4*side = 4*72 = 288 m

Let breadth of rectangle be x and length be 2x

Therefore perimeter of rectangle = 2(l+b) = 2(2x+x) = 2(3x) = 6x

6x = 288

x = 48m

Breadth = x = 48 m

Length = 2x = 2*48 = 96m

Area of rectangle = Length*breadth = 48*96 = 4608 sq.m
