The area of 1/2 cm wide frame = 48 - 35 = 13 cm²
Step-by-step explanation:
Length of rectangular picture frame = 6 cm
Width of rectangular picture frame = 8 cm
Area of rectangular picture frame = 6×8 cm² = 48 cm²
Length, excluding 1/2 cm wide frame of rectangular picture = (6–1/2-1/2) = 5 cm
Width, excluding 1/2 cm wide frame of rectangular picture = (8–1/2-1/2) = 7 cm
Area, excluding 1/2 cm wide frame of rectangular picture = 5×7 cm² = 35 cm²
Area of 1/2 cm wide frame = 48 - 35 = 13 cm²
Therefore, the area of 1/2 cm wide frame = 48 - 35 = 13 cm²
