Tiles are being placed in front of a fireplace to create a trapezoid hearth. The hearth will have a height of 24 inches and bases that are 48 inches and 60 inches. If the tiles cover 16 aquare inches, how many tiles will be needed?

Sagot :

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
81 tiles is the final solution b1= 48 in b2= 60 in h= 24 in and Area 1,296
