A rectangle cannot have an area of 40 cm since the units for area are cm2.
The following are some examples of rectangles with an area of 40 cm2:
10cm * 4 cm
1 000 cm * 0.04 cm
10*sqrt(2) cm * 2*sqrt(2) cm
10*pi cm x 4/pi cm
Basically, take any number, L cm, as length and let 40/L cm be the breadth.

Why won't squaring a side work with all rectangles to find the area?
Some rectangles don't have equal sides.
If 2 rectangles have the same area will they always be similar?
No some times
Do the rectangular parallelogram both have the same area explain why or why not?
No. A rectangle and a parallelograms are desciptions of quadrilateral shapes. There is no indication of the size of either. So some rectangles are smaller than some parallelograms and some parallelograms are smaller than some rectangles.
How can finding the area of a rectangle help you find the area of other shapes?
Some irregular shapes can be broken down into a combination of rectangles. Think of a solid "L" shape. It might be difficult to find the area of that. But if you think of it as two rectangles, it's a lot easier.
Are some parallelograms rectangles?
In fact, some are rectangles, but not all are.
Are some rectangles quadrilaterals?
All rectangles are quadrilaterals. A quadrilateral has 4 sides; all rectangles have 4 sides; thus all rectangles are quadrilaterals.
Are there some parallelograms that are rectangles?
All rectangles are parallelograms, so yes there are some.
What objects are 40cm?
Some objects that are around 40cm include a standard ruler, a small laptop, a basketball, and a medium-sized frying pan.
Are all parrellelograms rectangles?
No. Only some parallelograms are rectangles. But all rectangles are parallelograms.
Why are some rectangles squares?
All squares are rectangles also, but not all rectangles are squares, only equilateral rectangles are considered square.
All rectangles are rhombus?
No. Only some rectangles are - when they are squares.
Is a quadrilateral a rectangle?
Not all quadrilaterals are rectangles. Some quadrilaterals are rectangles, and the rest are not. However, all rectangles are quadrilaterals.
