a rectangle is 6 times as long as it is wide. the perimeter is 140 cm. find the area of the rectangle. round to the nearest tenth if necessary.

Answer 1

Answer: $w = 10$

Step-by-step explanation:

Our perimeter will be 140 cm and our width of the rectangle will be 6w. We will then divide 14w and 140 by 14 so we can get w by itself. Then, we will divide the perimeter by the width.

Step 1: Let 6w will be our length and let the perimeter be 140 cm.

$6w, P = 140 cm$

Step 2: Perimeter means that you add up all the 4 sides of the rectangle.

$P = 140 = w + w + 6w + 6w = 14w$

$P = 140, 14w$

Step 3: Divide both sides 14 to get the single w variable.

$\frac{140}{14} = \frac{14w}{14}$

Step 4: Simplify.

$10 = w$

Step 5: Flip sides.

$w = 10$
