Question

The perimeter of a rectangle is 343434 units. Its width is 6.56.56, point, 5 units. Write an equation to determine the length (l)(l)(, l, )of the rectangle. Find the length of the rectangle.

Answer 1

Explanation:

perimiter=2(Length+Width)

P=2(L+W)

solve for L

distribute

P=2L+2W

minus 2W

P-2W=2L

divide by 2

\frac{P-2W}{2}=L

given that P=34 units and W=6.5 units

\frac{34-2(6.5)}{2}=L

the equation would be L=p2w/2 or L= p/2=w
