Question

the length and the breadth of a rectangular field are in the ratio 5:4 if it's perimeter is 126 find the dimensions​

Answer 1

Answer:

Length = 35, Breadth = 28

Step-by-step explanation:

Let length and breadth be 5x and 4x respectively.

perimeter of the rectangle=2(l+b)

                                     126= 2(5x + 4x)

                                     126= 2(9x)

                                     126= 18x

                                  ⇒x = 126/18

                                     x = 7

Length = 5x = 5×7 = 35

Breadth = 4x = 4×7 = 28
