So the area of one triangle is (3.5 x 9 ) 31.5 , times that by 4 gives us 126 , now add that to 7 squared which is 126 + 49 . the answer is 175 cm^2<span />
A = 34 x 2 = 68
b = 56/2 = 28
hope it helps
Answer:
Step-by-step explanation:
Well asuming that is the picture for the reference, look and the line in the middle of the triangle.
it has and h for height next to it so tha means that is the height of the Musceu Blau.
ans. 180
-----------------------------------------------------------------------------------------------------------------If you are truly wondering the height of the Musceu Blau, then . . .
The Museu Blau in Barcelona, Spain, is a natural science museum built in the shape of a triangular prism. The building is an equilateral triangle 180 meters on each side and 25 meters high (this is the depth of the prism). The height of each triangle is 156m.
Length of MN = Length of M′N′ is the correct answer. Hope it helps :))
Width = w
Length = 3w - 6
Area = 360
Equation Area = wl
w (3w-6) = 360
3w^2- 6w = 360
3w^2 - 6w - 360 = 0
3 (w^2 - 2w - 120)=0
3(w + 10)(w - 12) = 0
w = -10 & 12
l = 3w-6 = 3 (-10)-6= -30 - 6= -36
l = 3w-6 = 3(12) - 6 = 36-6 = 30
Answer: -10 and 12. Yet, since this is a measurement, it must be positive so 12 ft
