Question

the length of rectangular field is hundred metre if its perimeter is 300 metre what is its breadth​

Answer 1

Answer:

50 metres

Step-by-step explanation:

Perimeter = 2(l + b)

300 = 2(100+b)

150 = 100+b

b = 50 metres

Answer 2

Answer: 50m

Step-by-step explanation: Length of rectangular field = 100m

Breath of the field = b

Perimeter of rectangle = 2(l+b) = 300m

                                    => 2l + 2b = 300

                                    => 2(100) + 2b = 300

                                    => 200 + 2b = 300

                                    => 2b = 300 - 200

                                    => 2b = 100

                                    => b = 100/2

                                    => b = 50m

Hence, the breath of the rectangle is 50m.
