Step-by-step explanation:
Area of polygon = area of square + area of triangle
Square:
Side = 12 cm
Area of square = side *side
= 12 * 12
= 144 sq.cm
Triangle:
base (b) = 12 cm
Height h = 19 cm

= 6 * 19
= 114 sq.cm
Area of polygon = 144 + 114 = 258 square cm

Answer:
8 weeks
56 days equals 8 weeks or 8x7 = 56
Step-by-step explanation:
Jeremy=x
Older sister=x+5
younger sister=x+5-9 or x-4
x+(x+5)+(x-4)=49
combine like terms
3x+5-4=49
3x+1=49
subtract 1 from both sides
3x=48
divide both sides by 3
x=16
Jeremy=16
Older sister=16+5=21
younger sister =16-4 or 16+5-9=12
J=16
OS=21
YS=12
76 -55= 21
76 is decreased by 21.
We initially start with 76, so now we have to divide 21 by 76:
21/76* 100%= 27.63%
Rounded to the nearest tenth, the final answer is 27.6%~
