Best Answer

Without using a graphing calculator the possible answer is:

length = 40 metres and width = 20 metres because:

Area = 40*20 = 800 square metres

Perimeter = 40+40+20+20 = 120 metres

Q: If the perimeter of a rectangle is 120 meters and the area is 800 meters squared how do you find length and width using a graphing calculator?

88mm squared

== 25x25== 625 Rectangle sides 5 cm each. ==

The dimensions of the rectangle are 3 inches by 14 inches

perimeter = (5+5+12+12)= 34 area = (5*12) = 60 squared

First divide the perimeter by 2 then subtract the diagonal from this. The number left with must equal two numbers that when squared and added together equals the diagonal when squared (Pythagoras' theorem) These numbers will then be the length and height of the rectangle.

The perimeter varies, depending on the shape.

To answer this simply try a few out for yourself. In a 2x1 cm rectangle, the area is 2 cm squared and the perimeter is 6 cm In a 12x10 rectangle, the area is 120 cm squared and the perimeter is 44 cm. In some cases, the perimeter is larger and in others it is smaller. To answer your question, no, the perimeter of a rectangle is NOT always greater than its area.

The perimeter is 18 feet.

First divide the perimeter by 2 then subtract the diagonal from this. The number left with must equal two numbers that when squared and added together equals the diagonal when squared (Pythagoras' theorem) These numbers will then be the length and height of the rectangle.

Area = 8*24 =192 square feet Perimeter = 24+24+8+8 = 64 feet

Rectangle with area 28 m2 and width = 4 m => length = 28/4 = 7m. Then, perimeter = 2*(4+7) = 2*11 = 22 metres.
