Question

the length of a rectangular field is twice its breadth if the area of the field is 288 square metre and find its perimeter​

Answer 1

Answer:

The Correct Answer is 72 m

Step-by-step explanation:

Let Breadth of the rectangle: x

Let Length of the rectangle is: 2x

The Area of the rectangle is: 288 $m^{2}$

Area = L X B

288 = x X 2x

288 = 2$x^{2}$

144 = $x^{2}$

12 = x

Breadth of rectangle is: 12 m

Length of rectangle is: 24 m

Perimeter of rectangle is = 2( L + B)

= 2 ( 12 + 24 )

= 2 ( 36)  

= 72 m
