It's just a tiny bit sloppy. The 10.2 cm should be designated with a right angle too. I'll answer it that way.
Area = (L1 + L2)*h/2
L1 = 10.2
L2 = 12.2
h = 12.6
all givens are in cm.
Area = (10.2 + 12.2)*12.6/2
Area = 22.4 * 6.3
Area = 78.12 cm^2
The first is an absolute value sign. But there is a - outside the first one so the -4 does become positive but then becomes negative again so you have -4
The second value is basically saying the same thing as -1x-4 which become a negative times a negative which is positive. You end up with 4.
So no it does not equal each other.
I do see an extra absolute value symbol though on the right side of the equal sign. But it looks like either way it would be -4 = 4 and that's not true. So either way it should be false.

The linear model for the data is expressed as: R = 20p - 160.
<h3>How to Write a Linear Model?</h3>
Using two pairs of values from the table values, say, (32, 480) and (33, 500), find the unit rate (m).
Unit rate (m) = (500 - 480)/(33 - 32) = 20/1
Unit rate (m) = 20.
Substitute (p, R) = (32, 480) and m = 20 into R = mp + b to find b
480 = 20(32) + b
480 = 640 + b
480 - 640 = b
b = -160
To write the linear model, substitute m = 20 and b = -160 into R = mp + b:
R = 20p - 160
