A postcard is in the shape of a parallelogram. A parallelogram is a quadrilateral with two pair of parallel sides, opposite sides and opposite angles are equal.
Since, the postcard has an area of 12 square inches.
Since, area of parallelogram = 
As area of parallelogram is 12, it means that the product of base and height is 12 square inches.
So, the possible dimensions of postcard are 3 inches and 4 inches and 2 inches and 6 inches.
So, base = 3 inches , height = 4 inches or base = 4 inches , height = 3 inches.
So, base = 2 inches, height = 6 inches or base = 6 inches , height = 2 inches.
Answer:
28%
Step-by-step explanation:
percent change in the number of bird droppings = increase in splatters / splatters counted on Monday x 100
x 100 = 28%
To find the median of 20 values, list the values from smallest to largest then add the 10th and 11th number then divide by 2 and you get your median.
If A is your age:
400 - 2A = 244
2A = 400 - 244
2A = 156
A = 78
To find the number of feet she jumped you have to divide 156 by 12 because there are 12 inches in a foot
So 156/12 =13
So she jumped 13 feet
