How do you find the width of a rectangle when the area and length are known'?
Rectangle ABCDArea=x__Length=ABWidth= x/AB
If the rectangle above has an area of 20 what is the length of side AB?
12
How to find area of rectangle on coordinate graph?
Suppose the sides of the rectangle ABCD are not parallel to the axis. Then if A = (p,q) and B = (r, s) then by Pythagoras, |AB|2 = (p - r)2 + (q - s)2 from which AB can be calculated. Calculate BC in a similar fashion and then area = AB*BC If AB is parallel to an axis (say the x axis), then q = s so that q - s = 0 and |AB|2 simplifies to (p - r)2 + 02 so that |AB| = |p - r|
What would the area of a rectangle be with a b equals 8in and a h equals 5in be?
Without knowing where a, b and h are, we have no way of knowing whether ab and ah are lengths, widths or diagonals and consequently, no way of determining the area.
Why are there six trigonometrics functions only?
All the trigonometric functions are derived from the right angled triangle. If we consider the three sides (AB, BC, CA) of a triangle and the included angle. There is a possibility of getting six functions based on the ratios like AB/AC, BC/AC, AB/BC, BC/AB, AC/BC, AC/AB . So we will have six trigonometric functions

How do you find the surface area of rectangular box?
A rectangular box has six sides. Find the area of them and add them together. Two sides are length times height, two sides are length times width, and two sides are width times height. Surface Area = 2LH + 2LW + 2WH
What is the relationship between the area of rectangle ABCD and the area of ABC?
Area of a rectangle = length of base x height Area of a triangle = (length of base x height)/2 A.............................................. B mmmmmmmmmmmmmmmmmmm m.............................................. m m ..............................................m m.............................................. m m.............................................. m m.............................................. m m ..............................................m m.............................................. m mmmmmmmmmmmmmmmmmmm C ..............................................D Area of ABCD = AB x AC Area of ABCD = (AB X AC)/2 Then Area of ABCD = 2 Area of ABC
How do you prove a quadrilateral is a rectangle?
You need to prove that there are two pairs of sides with equal lengths. Imagine a rectangle A C B D Since side AB is equal in length to side CD that is one equal pair. Likewise, AC is equal to BD and is the other equal pair. Since there are two equal parallel pairs, the angles must all be 90 degrees by rules of geometry so it is a rectangle. Note: The same thing may be used to prove a square, except a square has all sides of the same length. ================================================ If you can prove any one of these statements, then your quadrilateral is a rectangle: -- Opposite sides are parallel and any one angle is a right angle. -- Opposite sides are equal and any one angle is a right angle. -- All four angles are right angles. -- Adjacent angles are complementary, and one of them is a right angle. -- Opposite sides are either equal or parallel, and area is equal to the product of two adjacent sides. -- Diagonals are equal.
What is the formula for suface area of a rectangle?
The formula for a rectangle is height x width (A=ab)Since you said surface area, I'm pretty sure that you might mean a rectangular prism. To get this, you would need to find the area of each "rectangle side". To do this, you use the first formula, using height (a), width (b), and depth (c). The formula for theSurface Area of a Rectangular Prism = 2ab + 2bc + 2ac
Total surface area of a cuboid?
With sides of length A, B and C units, the total surface area is 2*(AB + BC + CA) square units.
Find the length of a rectangle that has a diagonal of 18.9 cm and a width of 6.7 cm?
A rectangle has all angles equal to 90*. So you can apply the Pythagoras theorem as the diagonal, length, and width form a right angle triangle -> AB²= BC² + CB² where AB is the hypotenuse ( side opposite to 90*), and BC and CD are the other two sides. So in your case 18.9²= Lenght² + 6.7². Length= √18.9²-6.7²= √357.21-44.89= √312.32= 17.672577627499617 cm is your answer.
How is segment AB congruent to segment BC in a rectangle?
if it is a square
What is a complex shape with an area of 105 cm and a perimeter of 100 cm?
It need not be a complex shape. You can have a rectangle with these properties. Just solve the two equations: 2a + 2b = 100 (for the perimeter) ab = 105 (for the area)
what is the included angle for sides AB?
B
