Help me with steps . Thanks

Answer 1

Answer:

135 cm

Step-by-step explanation:

1. Formula for area of a triangle: $\frac{1}{2}$ × $b$ × $h$
2. $\frac{1}{2}$ × $b$ × $h$ =
3. 18 × 15 = 270
4. Plug in 270: $\frac{1}{2}$ × $270$  
5. $\frac{1}{2}$ × $270$ =
6. $270$ ÷ $2$ = $135$

Answer 2

Answer:

135 square centimeters.

Step-by-step explanation:

The area of a triangle is given by the formula:

$A=\frac{1}{2}bh$

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:

$A=\frac{1}{2}(18)(15)$

Multiply:

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

The area of the triangle is 135 square centimeters.
