For perimeter just add the sides up.
a) P = 57 + 41 + 57 + 41 = 196 in
Ignore the 36 because it is not an edge
b) P = 56 + 73 + 92 = 221 in

For areas look for measurements at right angles and multiply them.
a) A = 57 x 36 = 2052 in^2
b) A = 1/2 x 56 x 73 = 2044 in^2
The half is needed because all triangles are half the area of a rectangle.

To find the average of a student’s test scores, add the scores and divide by the number of tests. Suppose Ryan scored 85, 92, 88

Lilit [14]

X= (85+92+88+98)/4
The slash means to divide. So you’re making a fraction with all the scores on top and the number of scores on the bottom.

Oliver uses the greatest common factor and the distributive property to rewrite this sum:

dalvyx [7]

The greatest common factor of 64 and 96 is 32, so, the first step after finding the great common factor is convert and rewrite "64 + 96" into distributive property.

You should get 32(2 + 3)
