Help me find N and get this right​
disa [49]

Answer:

N = 18

Step-by-step explanation:

The triangles are similar, thus the ratios of corresponding sides are equal, that is

\frac{5}{15} = \frac{6}{N} ( cross- multiply )

5N = 90 ( divide both sides by 5 )

N = 18

Please help im so confused asap
enyata [817]

Answer:

624

Step-by-step explanation:

the area of the triangles:

12*10 = 120

120/2 = 60

since there are 2 triangles of the same dimensions that make up the surface area 60 + 60 = 120

area of the rectangles:

13*14 = 182

since there are 2 rectangles of the same dimensions 182 + 182 = 364

The last rectangular:

10*14 = 140

add all areas:

120 + 364 + 140 = 624
