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.

How many acres are 310 feet * 630 feet
108,000 square feet or 2.479 acres.
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.
18.59 acres
About 17.2 acres.
