Question

Find the length of a rectangle whose breadth is 80 M and perimeter is 400 m ​

Answer 1

Step-by-step explanation:

perimeter = 2(l+b)

400 = 2(l+80)

400/2 = l+80

200 = l+ 80

200-80 = l

120 = l

Answer 2

Answer:

length=120m

Step-by-step explanation:

Given: Breadth:-80m

           Perimeter:-400m

Formula for perimeter of rectangle:-2*(l+b)

                    In(m)   Perimeter=2*(l+80)

                                400=2*(l+80)

                                400/2=l+80

                                200=l+80

                                 l=200-80

                                 l=120

The length of the rectangle would be 120m
