dont is answer

call width x so length is 3x perimeter is (2*length)+(2*width) so perimeter is 8x

2 times (length + width)

Area is length times width, perimeter is twice the sum of length and breadth.

The area is the length times the width. The perimeter is two times the length plus two times the width.

The perimeter of a rectangle is the distance around the rectangle. The area of a rectangle is the space inside the rectangle. To calculate either one you need the length and the width of the rectangle. To calculate the area multiply the length times the width. To calculate the perimeter add the length+width+length+width (that is the distance all the way around)

The perimeter is the sum of its 4 sides and its area is length times width

2 times length plus 2 times width = perimeterhalf the perimeter of a rectangle

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

Perimeter = (length+breadth) times 2 = (3 + 3/8) x 2 = 66/8 = 63/4

perimeter is the measure around the figure; area is the measure within the figure formula: perimeter: length+length+width+width=perimeter (for square or rectangle) area: length times width= area ( for square or rectangle)

perimeter 24 so length + width half of that ie 12. Length 3 times width must be 9 and width 3.

The distance around it, two times the sum of the length and width.

Perimeter= 2length x 2widthSince the perimeter is 40 and 2 times the width is 16, that means 2 times the length is 24. The length is 12.

Subtract two times the length from the perimeter and divide the remainder by two. This should be the width.

the answer to number 20 is B...12

The answer is centimetersImproved Answer:-The length works out as 9 and 1/3 cm

The perimeter of a rectangle is equal to 2*length + 2* width. In this case, we will say 2x + 2y = p = 48. Since the length is equal to 3 times the width, the equation now becomes p = 6*y + 2*y, or just p = 8y. Now since p =48, y must equal 6. And since the length is three times the width (y), the length is 18.

The area is the length times the width. The perimeter is two times the length plus two times the width.

Perimeter = length + length + width + width Let "w" = width, then "7w" must equal the length (because it's 7 times the width) 7w + 7w + w + w = perimeter 16w = perimeter

That would be 3 x 9 inches.
