90000 because 9 rounds up to 10, and so 89 rounds up to 90.
Here, as triangles are equal, their ratio would be equal.
8/x+4 = 12 /2x+1
8(2x+1) = 12(x+4)
16x+8 = 12x + 48
16x-12x = 48 - 8
4x = 40
x = 10
Hope this helps!
Answer:
24÷6+2= 6
Step-by-step explanation:
24÷6 is 4
4 + 2 is 6
The base is a square, therefore all the sides of the base are the same. This also means all the triangles have the same area.
10*10 = 100 cm^2 for the base
0.5*10*12 = 60 cm^2 for each triangle
100 + 4(60) = 340 cm^2
