Tiles are being placed in front of a fireplace to create a trapezoidal hearth. The hearth will have a height of 24 inches and bases that are 48 and 60 inches. If the tiles cover 16 square inches, how many tiles will be needed?
assume that the tiles can be cut remember that teh formula for a trapezoid is (base1+base2) times (1/2 height) height=24 base1=48 base2=60 subsitute (48+60) times (1/2 24) 108 times 12=1296 now wee find out how many tiles 16 is 1 tile find how many 16's in 1296 1296/16=81 ans: 81 tiles
