Question
The table given below contains some measures of the right angled triangle. Find the unknown values.
Base Height Area
20 cm 40 cm ?

Answer

Area of the right triangle $=\frac{1}{2} \times($ base $\times$ height $)$ unit $^2$
$b=20 cm$
$h=40 cm$
$\text { Area }=\frac{1}{2}(b \times h) cm ^2$
$=\frac{1}{2} \times 20 \times 40$
$=400 cm ^2$
$A=400 cm ^2$
Tabulating the unknown values
Base Height Area
20 cm 40 cm 400 cm^(2)
