Mathematics in the fifth grade of primary school. Are the two parallelograms at the bottom equal in area? What is their field?
The two parallelograms in the picture below have equal areas. Their areas are all equal to 1080 square centimeters.

The analysis process is as follows:

The two figures in the figure are both parallelograms, and the two parallelograms have a common edge, which can be regarded as the bottom. The vertical direction of 45cm is the height of these two parallelograms.

The bases of two parallelograms are equal and the heights are equal. So the area is equal.

Area of parallelogram = base times height =24cm×45cm= 1080 cm2.

Common perimeter area calculation formula:

1, the perimeter of the rectangle = (length+width) ×2. Letter expression: C=(a+b)×2

2. The circumference of a square = side length ×4. Alphabetic expression: C=4a

3. Area of rectangle = length × width. Letter expression: S=ab

4. Area of a square = side length × side length. Letter expression: s = a.a

5. Area of triangle = base × height ÷2. Letter expression: S=ah÷2

6. The area of parallelogram = base × height. Letter expression: S=ah

7. Trapezoidal area = (upper bottom+lower bottom) × height ÷2. Letter expression: s = (a+b) h ÷ 2
