First one :
We divide it into two rectangles (the top one has dimensions 2in*4in)
The area of the top rectangle is 2*4=8 in^2
The second rectangle has dimensions 3*(5-3)=6 in^2
Hence the total area is 8+6=14 square inches
Second one :
We divide it into a rectangle (dimensions 11*17) and a triangle on the top.
The area of the rectangle is 11*17=187 m^2
The rectangle has dimensions 17 (base's length) and 23-11 (height) hence its area is 17*(23-11)/2=102 m^2
Hence the total area is 102+187=289 square meters
The right answer is 19.9
Step-by-step explanation:
Given data set is;
(18, 23, 17, 25, 15, 18, 18, 16, 27, 25, 18, 19)
Sum of terms = 18+23+17+25+15+18+18+16+27+25+18+19 = 239
Number of terms in data set = 12
Average = 
Average = 
Average = 19.91
The average of data set is 19.91
The right answer is 19.9
