Question

▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁

Answer 1

Answer:

270 cm^2

Step-by-step explanation:

This is quite easy.

There is formula for it, the formula is bh/2

b= is the base or side that the triangle's altitude or height is perpendicular to.

h= is the height of the triangle or the altitude of the triangle.

I can always like to thing that a triangle is like half of a rectangle because the area for a rectangle is bh, but in a triangle it is half the bh.

b= 30

h=18

Now substitute the values in the formula

30(18)/2

30 times 18 = 540

divide the product by 2

540/2 = 270

Answer 2

$\sf b \: = 30 \: cm \\ \sf h = 18 \: cm \\ \\ \sf formula \: = \frac{bh}{2} \\ \\ \sf area \: \longrightarrow \\ \sf = \frac{bh}{2} \\ \sf = \frac{30 \times 18}{2} \\ \sf = \frac{540}{2} \\ = \underline{\bf 270 \: \: {cm}^{2} }$
