This question cannot be answered sensibly. An acre (not acer) is a measure of area, with dimensions [L2]. A foot is a measure of distance, with dimensions [L]. Basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.
136 centimeters = 4.46 feet.
136 meters = 446.19 feet.
136 meters = 446.19 feet.
1.18 acres = 51,400.8 sq feet.
To convert yards to acres, multiply the length by the width (in yards) and then multiply by 0.0002066. In this case, 136 yards by 58 yards equals 7.888 acres.
