The area of a trapezium is 128 cm2, the height is 8 cm, and the bottombase is 4 cm more than the top base. How many centimetres is the topbase? 答案 (128*2÷8-4)÷2=14(cm) 相关推荐 1The area of a trapezium is 128 cm2, the height is 8 cm, and the bottombase is 4 cm...
To use the Trapezium Rule to find the area of region A, you will need to divide region A into smaller trapezoids and calculate the area of each trapezoid using the formula A = 1/2 * (a + b) * h. Then, add up all the areas of the trapezoids to get an approximate value for th...

Trapezium (UK) Area = ½(a+b) × h h = vertical height Circle Area = π× r2 r = radius Ellipse Area = πab Sector Area = ½ × r2×θ r = radiusθ = angle in radians Note: h is at right angles to b Example: What is the area of this rectangle? The formula is...
Using trapezoidal rule to approximate the area under a curve first involves dividing the area into a number of strips of equal width. Then, approximating the area of each strip by the area of the trapezium formed when the upper end is replaced by a chord. The sum of these approximations ...
