Amount of material =area
area of triangle=1/2 times base tiems ehighte
base=2 and 1/4
height=8 and 1/2
convert all to imporpoert
2 and 1/4=2+1/4=8/4+1/4=9/4
8 and 1/2=8+1/2=16/2+1/2=17/2
so we have
area=1/2 times 9/4 times 17/2
area=(1 times 9 times 17)/(2 times 4 times 2)
area=153/16
area=9 and 9/16
answer is 9 and 9/16 square units of material
29 x 13= 3720 x 1= 3720 divide that by 10= 372 remove 3 so (7,2) is the slope roach
The diagonals are equal and they bisect each other.
BD=2BX=2(y+4)=2y+8
AC=BD
4y=2y+8
2y=8
y=4
38/244= about 0.16
24/943= about 0.03
653/53= about 12.32
