Question

the perimeter of the rectangle PQRS is 80cm .if PQ:QR=5:3,Find the length of PQ​

Answer 1

PQ=50 cm is the answer

Answer 2

Answer:

Length = 25 cm

Step-by-step explanation:

Perimeter = 80 cm

Measurement of PQ = 5x

Measurement of QR = 3x

Therefore , Length = 5x and Breadth = 3x

Perimeter = 2[l+b]

      80      = 2[5x+3x]

   80         = 2[8x]

    80        =  16x

       80/16   = x

          5        =  x

          5x = 5*5

                = 25 cm

            3x = 3*5 cm

                   = 15 cm
