Question

The area of a rectangular field whose length is 3 times its breadth, is 384 m². Estimate its length to the nearest whole number of metres.​

Answer 1

Answer:

Step-by-step explanation:

breadth= x

length = 3x

area = x* 3x = 384

        = 3x^2 =384

        = x*2 = 128

         x = $\sqrt{128}$

            =11.31 ....

length =  11.3 * 3 =  34 m
