Answer:
Perimeter = 98 cm
Area = 596 
Step-by-step explanation:
Please refer to the attached image for the resultant figure when a quadrant of circle with radius 7 cm is cut from a rectangle of sides 30 cm and 25 cm.
Perimeter of a figure = Sum of all its sides + Perimeter of circle
Quadrant of a circle is one fourth of a circle and there are 4 such quadrant of a circle, so eventually there is one complete circle in this figure.
The sides of this resultant figure = 30 - 14 = 16 cm
and 25 - 14 = 11 cm
So perimeter of this figure = 16 + 11 + 16 + 11 + Perimeter of circle

To find area of this figure = Area of rectangle - Area of circle
Area of rectangle = Length
Width

Area of circle =

So, area of figure = 750 - 154 = 596 
Answer:

Step-by-step explanation:
x and y could be negative or positive.
Answer:
27
Step-by-step explanation:
220-4=216
216/8=27
45/x =15/100
Cross multiply
15x=4500
Divide both sides by 15
X=300
300 total cars on parking lot
