Let ..
P = perimeter = 62
L= length = x+7
W = width = x

Solution:
  Since, the formula in getting the perimeter of rectangle is 2L+2W, therefore,
 P= 2(x+7) + 2(x)
 62 = 2x+7x+2x
 62 = 11x
 x= 5.6

L= 5.6+7
 L= 12.6

 To get the area, use the formula A=lw
 A= (12.6) (5.6)
A= 70.56  cm^{2}

 The area of the rectangle is  70.56 cm^{2} .
