Find The Width Of Rectangular Floor Is 16xsquared-1 And The Leghth Is 4x+1

Find the width of rectangular floor is 16xsquared-1 and the leghth is 4x+1

 

(I dont understand your question. It is either you are looking for the area and gave both dimensions of the sides or you are looking for the width and gave the area and the length.)

Calculating for the Area

Formula for the Area:

Area = length x width

A = (4x + 1)(16x² - 1)

A = (4x)(16x²) + (4x)(−1 )+ (1)(16x²) + (1)(−1)

A = 64x³ −4x + 16x² −1

A = 64x³ + 16x² −4x −1

The area is 64x³ + 16x² −4x −1.

Calculating for the Width

Formula for the Area:

Area = length x width

16x²-1 = (4x + 1)(w)

4x - 1 = w

The width is 4x - 1.
