the length of a rectangular deck is 4 times its width.
if the deck perimeter is 30 feet, what is the deck’s area?

The area of the deck is 36 square feet.

Solution:

Assume l is the length of the deck; w is its width, P is its perimeter and A is its area.

Given that length of a rectangular deck is 4 times its width

Perimeter of the deck is 30 ft

On substituting all the given values in (2) we get,

On dividing we get,

If w=3,

On substituting the values in the above formula we get,

1760 kilometers

step-by-step explanation:

multiply the amount of time the plane took to travel by it's speed

this shows a reflection over the x-axis and is translated one unit down and 6 units to the right (x + 6, y - 1)

hope this !
