If two rectangle have the same area must they have the same perimeter?
Not always because a 2 by 12 rectangle will have the same area as a 4 by 6 rectangle but they both will have different perimeters.
What is the perimeter of a rectangle whose area is 21?
That depends on the rectangle! You can have different rectangles with the same area, but with different perimeters.
How can the area of a rectangle stay the same when its length and width change?
Here's an example: A 4*4 rectangle has the same area as a 1*16 rectangle, but their perimeters are different.
Can you have a shape that has the same area but different perimeters?
Yes you can ex. square 4x4 16 ex. rectangle 8x2
Can a parallelogram and a rectangle have the same perimeters but different areas?
Yes.

A rectangle has a area of 36cm2 what are all the possible perimeters be?
24
Can a parallelogram and a rectangle have the same perimeters but different areas?
Yes.
If the area of the rectangle is 320cm squared find its perimeter?
Not enough data. Different rectangles (different length:width ratios) can have the same area, but different perimeters.
How two parallelograms could have the same area but different perimeters?
yes, for example:a 4 by 5 rectangle has an area of 20 and a perimeter of 18a 2 by 7 rectangle has an area of 14 and a perimeter of 18yes, for example:
Can two shapes have the same area and different perimeters?
Yes Example: Rectangle A has an area of 64 cm. and a perimeter of 32 8 cm. by 8 cm. Rectangle B has an area of 64 cm. and a perimeter of 40 4 cm. by 16 cm
What is the perimiter of 76 acres?
There is no simple relationship between area and perimeter. For the same area, you can have different perimeters, depending on whether the enclosed area is a square, a 2:1 rectangle, a 3:1 rectangle, etc., a circle, a 2:1 ellipse, a regular pentagon, etc.
Do squares with the same area have equal perimeters?
yes
Can shapes of the same area have different perimeters?
MOst of it
