Question

The width of a rectangle measures (8u-4)(8u−4) centimeters, and its length measures (8u-2)(8u−2) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?

Answer 1

Answer:Perimeter of a rectangle an quadrilateral is

P = 2( L + B ), the B can also be call the width. L = (8U - 4)(8U - 4) = (8U - 4)2 ie raised to the power of two. When this is expanded, it now becomes

64U2 - 64U + 16. The width

(8U -2)(8U - 2) = 64U2 -32U + 4

Now add the two together and multiply your result by two according to the formula

:P = 2(64U2 - 64U + 16 + 64U2 - 32U + 4)

= 2( 128U2 - 96U + 20)

= 256U2 - 192U + 40
