2 |
Hint |
Formula used |
\$"Area of Triangle" = (1/2) \times "base" \times "height"\$ |
3 |
Step |
From the diagram, the height of triangle |
\$30\$ |
4 |
Step |
From the diagram, the base of triangle |
\$30\$ |
5 |
Step |

\$"Area of Triangle" = (1/2) \times "base" \times "height"\$ |
6 |
Step |
On Simplification |
\$"Area of Triangle" = (1/\cancel2^1) \times \cancel(30)^15 \times 30\$ |
7 |
Step |
On Simplification |
\$"Area of Triangle" = 15 \times 30\$ |
8 |
Step |
