Answer 2

Answer:

.•♫•♬•Perimeter of Rectangle = 2x(l+b) Perimeter of Rectangle = 2X(12 1/2+10 2/3) Therefore Convert Mixed Fraction into Improper Fraction = 12 1/2 = 25/2 & = 10 2/3 = 32/3 = 2X(25/2+32/3) = For adding the fractions: Find LCM of Denominators(2&3) = LCM = 6 = 2X (25X3 + 32X2) = 75 + 64 (2X3 3X2 ) 6 = 2X139 = 278 = 139 6 6 3 = Therefore: Primeter of Rectagular Sheet= 139 3•♬•♫•.
