Exploring Area and Perimeter of Quadrilaterals and Triangles

The video tutorial covers the calculation of area and perimeter for quadrilaterals and triangles. It explains the formulas for area and perimeter, emphasizing the differences between shapes. For quadrilaterals, the area is calculated using base times height, while the perimeter is the sum of all sides. For triangles, the area is half the base times height, and the perimeter is the sum of all sides. The tutorial provides examples and clarifies the labeling of units for area and perimeter.

What formula is used to calculate the area of quadrilaterals?

• Base x Height

• Height / Base

• Length + Width

• Side x Side
