The given figure can be divided in two parts 1) Square with side 7 in 2) A right triangle with base 12 in and height 7 in.
1) Area of square =
Side of the square is 7 in.
Area =
2) Area of triangle =
Area of triangle =
Area of polygon= Area of square+ Area of triangle
Area of polygon = 49+42 =91 square in.
Area =
Answer:
The probability of cured people in who took the remedy is 8/9.
Step-by-step explanation:
Success rate of the cold remedy = 88%
