Answer: No question but I'll say what I know to try to answer your question. Triangles are 3 sided shapes with at least one 45 degree angle. There are types of triangles such as isosceles, scalene, and equilateral triangles.

Answer:

Step-by-step explanation:

B = 377lw

I will use L for length instead of l.

B = 12,252.5 BTU

w = 5 m

First, we find the length.

12,252.5 = 377(L)(5)

12,252.5 = 1885L

L = 6.5

The length is 6.5 m. The width is 5 m.

A = LW = (6.5 m)(5 m) = 32.5 m^2
