Bài 4: Trang 174 - sách giáo khoa (SGK) toán tiếng Anh lớp 4Given the shape H made by parallelogram...

By following these steps, we can accurately calculate the area of shape H formed by parallelogram ABCD and rectangle BEGC.

After calculating the area of both parallelogram ABCD and rectangle BEGC, we add the two areas together to get the total area of shape H.

The area of rectangle BEGC is calculated by multiplying the length by the width. In this case, length = BE and width = BC.

The area of a parallelogram is calculated by multiplying the base by the height. In this case, base = BC and height = BD.

To calculate the area of shape H, we need to find the combined area of parallelogram ABCD and rectangle BEGC.
