Question

A 300 metre long wire is used to fence a rectangular plot whose length is twice its breadth find the length and breadth of the plot​

Answer 1

Answer:

Step-by-step explanation:

let the breadth= A

therefore length=2A

perimeter=2(l+b)=300

                 2(A+2A)=300

                 3A=150

                 A=50

length=100m

breadth=50m

Answer 2

Step-by-step explanation:

Let the breadth of the rectangular plot = B

Then, the length of the rectangular plot = 2B

Perimeter of the rectangular plot = 300 m

2 (2B + B) = 300

2 * 3B = 300

6B = 300

B = 300/6

B = 50m

Length = 2B = 2 * 50 = 100 m

∴ The length of the rectangular plot is 100 m and its breadth is 50 m.
