The area of a rectangle is A = lw. 'A', the area, is 3927, and 'w', the width, is 51. By substituting the values in, we get that 3927 = 51L. Dividing both sides by 51, we get that L, the length, is 77.
q= -1/2
perpendicular slopes are those that are opposite sign and reciprocal of the original given slope
36 squared is 6
6x6 = 36
6 multiplied by itself is 36
6^2
for example
to find the sq root of 25...
5x5 = 25
so the sq root of this example is 5...
