分别测量2个对角线的长度。菱形的对角线就是对角中分线的连线。两条对角线是一种垂直关系，相交形成的4个三角形都是垂直三角形。
咱们假设对角线长度分别为6cm和8cm。WH.performance.mark(‘step1_rendered’);

两条对角线的长度相乘。这样我们得到6 cm x 8 cm = 48 cm2分别写下两个对角线的长度，两者相乘。这样的话，可得到6 cm X 8cm =48cm2,即此菱形的面积。单位是平方厘米。

把相乘得到的结果即48 cm2除以2，得到24 cm2。这个结果即是菱形的面积。即24平方厘米。

测量底边边长和垂直高度。你可以理解为底边长乘以垂直高度。假设菱形的高度是7cm，边长为10cm。

两个长度相乘。一旦你知道了菱形的边长和高度，你只要把两个数值相乘就可以了。所以10 cm x 7 cm = 70 cm2。这个菱形的面积就是70平方厘米。

计算任意边长的平方值。由于菱形的四个边长度相等，所以你选哪个边都一样。假设边长为2cm。 2 cm x 2 cm = 4 cm2。

用得到的数值乘以其中一个角的正玄值。选择哪个角都可以。让我们假设其中一个角的正玄值为33度。用正玄值乘以4 cm2，即(2 cm)2 x sin (33) = 4 cm2 x 1 = 4 cm2。得到的结果4 cm2即这个菱形的面积。
