Answer:
The area of the rectangle is 5050.35 mm or 505.035 cm.
Step-by-step explanation:
Given the perimeter and the length, to find the area of the rectangle, let's find the width first:
Perimeter = 2(Length)+2(Width)
285.6 mm = 2(78.3 mm) + 2W
285.6 mm = 156.6 mm + 2W
285.6 mm - 156.6 mm = 2W
129 mm = 2W
W = 64.5 mm
Since we have the width already, let's find the area!
Area = Length × Width
Area = 78.3 mm × 64.5 mm
Area = 5050.35 mm
Converting mm to cm, the area eould be 505.035 cm.
