What is the length of a rectangle that has a perimeter of 36 cm and a width of 8 cm?
perimeter = 2*width + 2*length 36= 2*8 +2*length2*length=36-162*length=20length = 10 cm
What is the answer to this math problem The area of a rectangular computer screen is 4x2 plus 20x plus 16 The width of the screen is 2x plus 8 What is the length of the screen?
Area = 4x2 + 20x + 16 Width = 2x + 8 Length = ? To begin, we will factorise all the expressions Area = 4(x2 + 5x + 4) = 4(x+1)(x+4) Width = 2(x+4) Length = ? The formula for Area is given by: Area = Length . Width (A dot has been used to represent multiplication in the above formula so as not to confuse it with the variable x) Substituting in our expressions for Area and Width gives: 4(x+1)(x+4) = Length . 2(x+4) Dividing both sides by 2(x+4) to solve for Length gives an answer of: Length = 2(x+1) If you look at the width and the length expressions, the width is longer than the length (which shouldn't be possible). It is most likely a mistake in the question.
How do you draw a rectangle with a perimeter of 12 units and an area equalling 8?
The rectangle would have a width of 2 and a length of 4.
A room on a floor plan has a length of 5 centimeters and a width of 8 centimeters. If the actual length of the room is 15 feet which proportion can be used to find the actual width of the room?
1 cm means 3 feet and so 8 times 3 = 24 feet
What is Length and width of a rectangular lot with a perimeter of 88 meters if the length is 4 meters more than the width?
The perimeter is L(length) x 2 + W(width) x 2 So 2L + 2W = 88 And L = W+4 So we can now replace the L in the equation and we get 2(W+4) + 2W = 88 Work out the brackets and we get 2W + 8 + 2 W = 88 Subtract 8 from both sides, and we get 2W + 2W = 80 or, 4W = 80 so we can divide both sides by 4 and we get W = 20 So now we can add 4 to the width and we get the length as 24. Now, to check the calculation, we add them all up Length 1 = 24 Length 2 = 24 Width 1 ==20 Width 2 ==20 Perimeter - 88
If A (-2 -4) and B (-8 4) what is the length of line AB?
End points: (-2, -4) and (-8, 4) Length of line AB: 10
If A is the point -2 -4 and B is -8 4 what is the length of AB?
Endpoints: A (-2, -4) and B (-8, 4) Length of AB: 10 units
If A is the point -2 -4 and B is the point -8 4 what is the length of AB?
Using Pythagoras Length AB = √((-8 - 2)² + (4 - -4)²) = √(6² + 8²) = √100 = 10 units.
What is the area of a 2 x 4?
It depends on the length. The surface area would be 4*length+8*length+16.
What happens to the perimeter of the rectangle if the length is decreased by 4 cm and the width is increased by 2 cm?
The perimeter decreases by 4. Decreasing the length by 4 decreases the perimeter by 8. Increasing the width by 2 increases the perimeter by 4. -8+4=-4 For example: Area of a rectangle could be: 8 x 6 (8 being the length and 6 being the width). The perimeter is 8+8+6+6=28 If the length is decreased by 4 then it becomes 4 If the width is increased by 2 then it becomes 8. The perimeter becomes 4+4+8+8=24
If A (-2 -4) and B (-8 4) what is the length of?
The length is 3*sqrt(5) = 6.7082, approx.
If A 0 0 and B 8 2 what is the length of ?
(0,8)2 + (0,2)2 8(2=69 2(2=4 69+4=74√
If A (-2 -4) and B (-8 4) what is the length of Ab?
Using the distance formula the length of ab is 5 units
The ellipse is centered at the origin The length of its horizontal axis is 4 and the length of its vertical axis is 8 What is the equation for the ellipse?
X^2/2^2 + y^2/4^2 = 1
What is the difference in length between a 5 out of 4 inch and a 3 out of 8 inch?
5/4 in - 3/8 in =((5×2)/(4×2) - 3/8) in = (10/8 - 3/8) in = (10-3)/8 in = 7/8 in
If A(-2-4) and B(-8-4) what is the length of AB?
AB can be found by using the distance formula, which is the square root of (x2-x1)^2 + (y2-y1)^2. In this case, AB= the square root of (-2-(-8))^2 + (-4-(-4))^2 which AB= the square root of 64 + 0 which AB=8.
How do you find one half the length of 8?
You divide it by 2, so the answer is 4.
