Length of a rectangle is four times its width if the area of the rectangle is 196 yards find its perimeter
jeka94

Answer:

22 yd

Step-by-step explanation:

Length is four times its width   ----->    L=4W

area of rectangle is 196           ----->   196=LW

Plug L=4W into 196=LW giving you 196=(4W)W

Simplify a bit 196=4W^2

Divide both sides by 4:   196/4=W^2

Simplify a bit:   49=W^2

Square root both sides:  7 or -7=W

The width is 7 yd

The length is 4(7)=28 yd

Now its final part is for you to find the perimeter of this rectangle.  The rectangle is a 7 yd by 4 yd rectangle.

Double both then add.. 14+8=22 yd

Anastasy [175]

No she is not because 1 2/5 is a bigger number than 5/7.

1 2/5 in decimal form is 1.4, and 5/7 in decimal form is .714.
