l=2*w+2 Perimeter P=2*l+2*w = 2(2w+2)+2w = 4w+4+2w = 6w+4 = 64 meters 6w=60 meters w=10 meters l=2*w+2 = 2*10+2 = 22 meters
L + W = 11 so L = 11 - W; L = 2W + 2; so 11 - W = 2W + 2 add W to each side: 11 = 3W + 2 subtract 2 from each side: 9 = 3W divide each side by 3: W = 3 so L = 8 m
length = w + 3area = 108area = w * (w + 3)108 = w^2 +3ww^2 + 3w -108 = 0w = 9 or -12The width is 9 meters, the length is 12 meters.
use pythagorean theorem where a2+b2=c2 (w+2)2+w2=102 2w2+4x+4=100 2w2+4x-96=0 divide by 2 w2 +2x-96=0 factor it (w-6)(w+8)0 you're answer is 6 centimeters because it can't be negative lol i posted this question and then figured it out :D
Given: 2w + 2l = 34 l = w + 2 Then: 2w + 2(w + 2) = 34 4w = 30 w = 7.5 l = 9.5
A = L x W 20 = 10 x W 20/10 = W 2 = W
l=2*w+2 Perimeter P=2*l+2*w = 2(2w+2)+2w = 4w+4+2w = 6w+4 = 64 meters 6w=60 meters w=10 meters l=2*w+2 = 2*10+2 = 22 meters
The cube has 6 faces. Area of the 6 faces = (6 x 200 x 200) = 240,000 square centimeters = 24 square meters Volume = L W H = (200 x 200 x 200) = 8,000,000 cubic centimeters = 8 cubic meters ============================================== Easier way to do it: 200 cm = 2 meters Area of one face = 2 x 2 = 4 square meters Area of 6 faces = 6 x 4 = 24 square meters Volume = 2 x 2 x 2 = 8 cubic meters
The area is L * W = 82.25 * 40.5 = 3331.125 sq cm The perimeter is 2(L + w) = 2 * (82.25 + 40.5) = 2 * 122.75 = 245.5 cm
L + W = 11 so L = 11 - W; L = 2W + 2; so 11 - W = 2W + 2 add W to each side: 11 = 3W + 2 subtract 2 from each side: 9 = 3W divide each side by 3: W = 3 so L = 8 m
Assume the room is rectangular. If the width is w then the length is w + 1. The perimeter is 2w + 2(w + 1) = 4w + 2. 4w + 2 = 14 : 4w = 12 : w = 3 meters
The dimensions of this rectangle are that its length is equal to 16 centimeters and its width is equal to 9 centimeters. To find these answers, you need to solve for two unknowns L and W in the equations L- W is equal to 7 and 2 x L plus 2 x W is equal to 50, where L is length and W is width.
length = w + 3area = 108area = w * (w + 3)108 = w^2 +3ww^2 + 3w -108 = 0w = 9 or -12The width is 9 meters, the length is 12 meters.
The perimeter of a rectangle is calculated by adding up the lengths of all its sides. In this case, the length is 15 centimeters and the width is 10 centimeters. To find the perimeter, you would add up all four sides: 15 cm + 10 cm + 15 cm + 10 cm = 50 cm. Therefore, the perimeter of the rectangle is 50 centimeters.

if width is equal to W and length is equal to L, then W x L = 80 L = W +2 so W x (W+2) = 80 solve to find W=8 and L= 10
Let x be L, so W = x - 2 P = 2(L + W) substitute 28 for P, x for L, and x - 2 for W; 28 = 2(x + x - 2) divide by 2 to both sides; 14 = 2x - 2 divide by 2 to both sides; 7 = x - 1 add 1 to both sides; 8 = x x - 2 = 8 - 2 = 6 So L = 8 cm and W = 6 cm. A = LW = 8 x 6 = 48 Thus the area is 48 cm^2
