Add together the lengths of each of its sides.
The volume v of a solid rectangle is lenght x width x height v = lwh for example if l = 10 and w = 5 and h = 1 then volume = 10x5x1 = 50
There is no "height" of a rectangle, unless it's a rectangular prism. Do you mean the length? If you have the area of the rectangle, the equation should be:A= L x WPlug in the area and the length and solve for the width, or plug in the area the width of the rectangle, and solve for the length.
Area of a rectangle is length x width. It isn't clear what the width is in this case - or how you could solve for it.
You take the formula for a rectangle, replace what you know, and solve for the remaining variable.
More information is needed to solve this problem
Make sure you know the length and width of the rectangle in the SAME UNITS ... both in inches, or both in meters etc. Then just multiply the two numbers ... Length x Width. The answer is the area of the rectangle.
Write two simultaneous equations and solve them. One for the perimeter, one for the area.
Very hard question, It took me one hour to solve it. I think it is 0.12 m or 120 mm.
Write an equation for the perimeter, and solve it. Remember that the perimeter is the sum of all four sides.
You must first calculate the width, using the formula for the area of a rectangle (plug in the numbers you know into the formula, and solve for width). Once you know this, you can plug in the numbers in the formula for a rectangle's perimeter.
if it is 90 degrees.it means that it look like its corner of a square or a rectangle.
You solve the area of square units by multiplying the legnth and the width of the square/rectangle. For different shapes there are different formulas, but I just gave you the most basic one.
For a rectangle, it is 2(l + w) l = length w = width
If it is a rectangle and not a square there is not enough information to solve this problem for area. Perimeter is 2( B+H) = 46 Area = BH
A rectangle by definition has two pairs of sides with equal length. Since perimeter equals the length of all the sides. The equation for the perimeter of a rectangle could be thought of as: 2L + 2W = P Where L represents the length of one side of the rectangle and W represents the length of the adjacent (next to) side of the rectangle. If you know the length of one side and the perimeter, plug those values in as L and P and then solve for W. That will give you L and W which are the dimensions of the rectangle.
To solve this, simply add 92 and 46 together, then multiply the result by 2. The addition will result in 138, and the multiplication will result in 276 so the perimeter is 276
To solve this group together the like terms. 7p + -p = 6p Then the answer is 6p -9.
