Answer:
A. 13m
Step-by-step explanation:
To find the area of a square you multiply Length by the Height. Since squares have equal length sides the number has to be the same for the length and the height.
13 x 13 = 169

It’s 24 because it’s half of base times height

Answer:
(D)
Step-by-step explanation:
The graph shows the arm span lengths of the students, clearly we can see that the most of the students have arm span length in the initial points of the length.
Median = Middle frequency of the data. Here, median will be the length in the middle.
Mode = Most frequently occurring number in the data. Here the mode will be the length which most of the students has.
Clearly, most of the student has the length in the initial inches while the median will be in the middle.
Hence, mode will be less than the median.
Answer:
Step-by-step explanation:
2[n+(n+0.6)]=2[2n+(n+0.1)]
2n+0.6=3n+0.1
3n-2n=0.6-0.1
n=0.5
perimeter=2[2n+0.6]=2[2×0.5+0.6]=2×1.6=3.2
