Question

find the area of the shaded triangle.
8 m
5 m
enter the correct answer in the box.
□ m²

Explanation:

Step1: 确定三角形底和高

观察图形,阴影三角形的底为长方形长的$\frac{1}{2}$,即$\frac{8}{2}=4\ \text{m}$,高等于长方形的宽$5\ \text{m}$。

Step2: 代入三角形面积公式

三角形面积公式为$S=\frac{1}{2} \times 底 \times 高$,代入数值:
$S=\frac{1}{2} \times 4 \times 5$

Step3: 计算面积

先算$4 \times 5=20$,再算$\frac{1}{2} \times 20=10$
