These cases ended 'separate but equal' in graduate and professional education. In Brown v. Board of Education, 347 U.S. 483 (1954), attorneys for the NAACP referred to the phrase equal but separate used in Plessy v. Ferguson as a custom de jure racial segregation enacted into law.
âºâº Definition: Acre. An acre is a measure of land area in Imperial units or U.S. customary units. It is equal to 43 560 square feet, 4840 square yards, or 160 square rods. The precise meaning of this depends on the exact definition adopted for a foot: the international acre is 4 046.856 422 4 m (for the UK, see).
Acres to square feet (ac to ft2) area units conversion factor is 43560. To find out how many square feet in an acre, multiply by the conversion factor or use the converter. 1 Acre = 43 560 Square Feet There are 43560 square feet in an acre, because an acre is defined as an area of 1 chain by 1 furlong (66 feet * 660 feet), that makes 66 ft * 660 ft = 43560 sq. feet in an acre.
