Question

Help me with steps . Thanks

Answer 1

135 cm

Explanation:

1. Formula for area of a triangle:
   `(1)/(2)` ×
   `b` ×
   `h`
2. 
   `(1)/(2)` ×
   `b` ×
   `h` =
3. 18 × 15 = 270
4. Plug in 270:
   `(1)/(2)` ×
   `270`
5. 
   `(1)/(2)` ×
   `270` =
6. 
   `270` ÷
   `2` =
   `135`

Answer 2

135 square centimeters.

Explanation:

The area of a triangle is given by the formula:

`A=(1)/(2)bh`

Where b is the base length and h is the length of the vertical height.

From the triangle, we can see that the base is 18 and the vertical height is 15. Thus:

`A=(1)/(2)(18)(15)`

Multiply:

`A=(9)(15)\\A=135\text{ cm}^2`

The area of the triangle is 135 square centimeters.
