QUESTION 1
Easy
Find the area of triangle ADE in the given figure.
SOLUTION
From figure,
Base \(= 8\,cm\)
Height \(= 10\,cm\)
\(\begin{aligned} Area &= \frac{1}{2}\, ×\, Base\, × \,Height \\ &= \frac{1}{2}\,×\,8\,×\,10 \\ &= 40\,cm^2\end{aligned}\)
The area of triangle ADE is 40 cm\(^2\).
Base \(= 8\,cm\)
Height \(= 10\,cm\)
\(\begin{aligned} Area &= \frac{1}{2}\, ×\, Base\, × \,Height \\ &= \frac{1}{2}\,×\,8\,×\,10 \\ &= 40\,cm^2\end{aligned}\)
The area of triangle ADE is 40 cm\(^2\).
🏆
Final Answer : The area of triangle ADE is 40 cm\(^2\).
Concept Note
The area of a triangle is given by
\(Area\, =\,\frac{1}{2}\,×\,Base\,×\,Height\)
