Answer:

Step-by-step explanation:

Assume that each cell on the grid represents one unit. One can use the formula, ( $A=\frac{(base)(hieght)}{2}$ ) to find the area of the triangle. One can see that the base of the triangle is, (11), and the height is (6). Substitute in the given values and solve for the area,

$A=\frac{(11)*(6)}{2}$

$A=\frac{66}{2}$

$A=33$

Answer:

a) 12cm

b) 360cm²

c) 2160cm cubed

Step-by-step explanation:

you would use Pythagoras theorem for A

so half of 18 is 9

15² - 9² = 144

the square root of 144 is 12

the height is 12cm

18 x 20 = 360cm²

csa x L

csa = b x h divide by 2

18 x 12 = 216cm²/2 = 108cm²

108xm² x 20cm = 2160cm cubed
