The floor of a trianaglular room has an area of 32 1/2 sq. M. If the triangle altitude is 7 1/2 m weite an equation to determine the length of the base, b, in metere. Then solve the equation

You must follow the proccedure shown below to solve this problem:

You have that the floor of a triangular room has an area of 32 1/2 m ² If the triangle altitude is 7 1/2 m. Then, you have:

A=32 1/2 m ²=32.5 m²

h=7 1/2 m=7.5 m

Now, you can calculathe b as below:

A=bxh/2

b=Ax2/h

When you substitute the values, you obtain:

b=32.5 m²x2/7.5 m

b=65 m²/7.5 m

b=8.66 m
