Answer:

Perimeter: 8x+20

Area: 3x^2+22x+24

Step-by-step explanation:

The perimeter of a rectangle is 2l+2w, which in this case is 2(3x+4)+2(x+6)=6x+8+2x+12=8x+20. The area is length times width which in this case is (3x+4)(x+6)=3x^2+22x+24. Hope this helps!

The Washington Monument in Washington, D.C., is about 556 ft. tall. A three-dimensional puzzle of the Washington Monument is 24

Umnica [9.8K]

Set up a ratio. But first convert the height of the puzzle to feet so we are comparing the same unit of measure.

STEP 1
convert 24 inches to feet

12 inches= 1 foot

24 inches= 2 feet

STEP 2
set up ratio.

= 2 feet/556 feet or 2:556
simplify both by 2

= 1 ft/278 ft or 1:278

ANSWER: 1/278 or 1:278 (can be written either way)

Hope this helps! :)
