Question

find the area of triangle whose base 4 cm height 9 cm
​

Answer 1

Answer:

18 is the answer

Step-by-step explanation:

Area of triangle 1/2×h×b

1/2×4×9

=18

Answer 2

Given : Base = 4 cm and Height = 9 cm

To Find : Area of triangle

⠀⠀⠀_______________________

${\boxed{\frak{\purple{Area~ of~ triangle~ = \dfrac{1}{2} × base × height}}}}$

$:\implies\sf{\dfrac{1}{2}×4×9}$

$:\implies\sf{2×9}$

$:\implies\sf{18 cm}$

$. \dot \ .$ ${\underline{\textsf{Hence,Area~ of~ triangle~ is {\textbf{18 cm}}}}}$.
