No, a 2 by 4 rectangle is not congruent to a 4 by 8 rectangle. They are similar, but the 4 by 8 rectangle is 4 times bigger than the 2 by 4.

The length and width of a rectangle are 8 inches and 4 inches respectively What would be the area of one of the triangles formed from drawing a diagonal in the rectangle?
A=l*w A=8*4 A=32 diagonal cuts the rectangle into two congruent triangles. 32/2 = 16
How do you find the area of a rectangle?
Area of a rectangle= length x height.For example:A 2' by 4' rectangle would have an area of 2 x 4 = 8 square feet.As a formula, it is L*W=A.
Can rectangles with the same perimeter have different areas?
Yes. Say there are two rectangles, both with perimeter of 20. One of the rectangles is a 2 by 8 rectangle. The area of this rectangle is 2 x 8 which is 16. The other rectangle is a 4 by 6 rectangle. It has an area of 4 x 6 which is 24.
The length and width of a rectangle are consecutive even integers The area of the rectangle is 8 square units What are the length and width of the rectangle?
Length = 4, Width = 2
What is the area of a rectangle if it is 4 meter long and 2 meter wide?
8 square meters
If you divide a 4 in by 8 in rectangle what new shapes do you get?
A 2 inch by 4 inch, but they are not congruent because they aren't the same size.A congruent shape means the same size and same shape.

If you divide a 4 in by 8 in rectangle from corner to corner what new shape do you get?
You get two congruent right triangles when you divide a rectangle diagonally. (This is one way to show that the area of each of those triangles is 1/2*base*height. Rectangle area = (4 in)(8 in) = 32 in2. Triangle area = (1/2)(4 in)(8 in) = 16 in2.)
If you divide a 4 inch by 8 inch rectangle from corner to corner what new shapes do you get?

What is the area of a rectangle that is 4 by 2?
The area of rectangle is : 8.0
What are 10 properties of a rectangle?
1. Opposite sides are equal 2. it is a parallelogram 3. all 4 angles (at vertices) are 900 4. diagonals are equal in length 5. diagonals bisect each other 6. triangles formed by a diagonal and 2 sides (opposite side for each triangle) are congruent 7. among the four triangles that are formed by the 2 diagonals, the vertically opposite triangles are congruent 8. if length=breadth, then the rectangle is a square 9. perimeter of the rectangle = 2 * ( length + breadth) 10. area of rectangle = length * breadth
Why is possible for two shapes to have the same area but different perimeter?
It is possible for to shapes to have the same area but different perimeters because, for example, one shape could be a 2 by 4 rectangle and another shape be a 1 by 8 rectangle. Both shapes have an area of 8 (2*4=8 and 1*8=8) but the 2 by 4 has a perimeter of 12 (2+2+4+4=12) but the 1 by 8 rectangle has an area of 18 (1+1+8+8=18).
What closed 4- sided figure has 4 right angles and 4 pairs of congruent sides?
I assume you mean 4 congruent sides or 2 pairs of congruent sides.. (There are no 4-sided figures with 8 sides.) A square.

What is the perimeter of a rectangle measuring 8 units on 2 sides and 4 units on 2 sides?
Perimeter is equal to the sum of all sides, in this case 2 of the length of the rectangle plus 2 of its width: 2*8 units +2*4 units ______ 16 + 8 =24 units
