perimeter (P)=2(length+base)
find length,
area = length * base = (p/2-base)*base

Why is the area of a rectangle base times height?
A rectangle is a good, simple shape to begin with. The area of a rectangle is equal to the product of the length of its base and the length of its height. The height is a segment that is perpendicular to the base. For a rectangle, the base and height are often called the "length" and the "width", and sometimes the height is referred to as the "altitude."
Surface area prism?
2*Area of Bases + Perimeter of base*Length.
How do you find the height of a rectangle with the base and perimeter given?
Height = (Perimeter/2) - Base
What is the area of a rectangle with perimeter 126.6 mm and base length 40.4 mm?
Area = Length times width.We know the length, but not the width. We can solve for it using 2l + 2w = p.(l = length, w = width, p = perimeter)This gives us 2(40.4) + 2w = 126.6.Solving for w gives us w = 22.9A = lw, so area = (40.4)(22.9), which is 925.16 mm2.
What is the area of a rectangle with a base of 10 and a height of 7?
The area of a rectangle is length x width. The area of a triangle is 1/2 base x height. If you mean a rectangle, the area is 70 square units. If you mean a triangle, the area is 35 square units.
What is the area of a rectangle with perimeter 126.6mm and base length 40.4mm?
It is: 22.9*40.4 = 925.16 square mm
When finding an area do you add all the sides up?
No that gives you the perimeter. The area depends on the shape. For example the area of a square is length of the side squared, and the area of a rectangle is the length of one side times the length of the base.
How do you calculate the area of the base in a rectangle?
The base of a rectangle is a length and does not have any area. Therefore, the area can not be calculated.
What is the height of a rectangle with perimeter 118.8mm and base length 15.1?
44.3 mm
How do you find the perimeter of a 7 in by 25 in base?
To find the perimeter of a rectangle simply add the length and width then double your answer.
What is the area of a rectangle with a perimeter of 285.6 mm and base length of 78.3?
Its width workks out as 64.5 mm and so area is: 64.5*78.3 = 5050.35 square mm
Why is the area of a rectangle base times height?

How do you get the area and perimeter of a rectangle?
area = base X height if rectangle is 4 inches by 8 inches it the area would be 32 inches perimeter = sum of the length of the 4 sides...so in the rectangle above you have 2 sides at 4 inches and 2 sides at 8 so the total of those 4 sides will be 24 inches
How do you find the answer of the base area of a rectangular prism?
The base of a rectangular prism is a rectangle. The area of a rectangle is length times width.
How do you get the area of rectangle?
lxb (length x base)
What is the formula of surface area of the prism?
Surface Area = 2 × Base Area + Base Perimeter × Length
How do you find perimeter and area of circle triangles and quadrilateral?
Circle:-- Perimeter ("circumference") = (pi) x (diameter) or (2 pi) x (radius)-- Area = (pi) x (radius)2 or (1/4 pi) x (diameter)2Triangle:-- Perimeter = (length of Side-#1) + (length of Side-#2) + (length of Side-#3)-- Area = 1/2 (length of triangle's base) x (triangle's height)Quadrilateral:Perimeter-- Any quadrilateral:(length of Side-#1) + (length of Side-#2) + (length of Side-#3) + (length of Side-#4)-- Parallelogram, rectangle, or kite: 2 x (length of 1 long side + length of 1 short side)-- Rhombus or square: 4 x (length of any side)Area-- Parallelogram, rhombus, rectangle, square: (length of base) x (height)-- Rectangle, square: (length) x (width)-- Square: (length of any side)2-- Trapezoid: 1/2 (height) x (length of Base-#1 + length of Base-#2)
