Answer:

The base b is 6m

Step-by-step explanation:

The area A of a triangle with base b and height h is given by the formula;

[tex]A=\frac{1}{2}*b*h[/tex]

The area of the triangle is given as 45 while the height h is 15. We substitute these known values into the formula above and solve for the unknown base;

[tex]45=\frac{1}{2}*b*15\\\\90=15*b[/tex]

We finally divide both sides by 15 to solve for b;

b = 90/15 = 6

Therefore, the base of the triangle is 6 m

Answer:

[tex]b = 6\ m[/tex]

Step-by-step explanation:

The area of a triangle is

[tex]A = 0.5b * h[/tex]

Where b is the base of the triangle and ha is the height.

In this case we have a triangle with area

[tex]A = 45\ m ^ 2[/tex]

and with height:

[tex]h = 15\ m[/tex]

So the base of the triangle is:

[tex]45 = 0.5b (15)\\\\b=\frac{45}{15*0.5}\\\\b=6\ m[/tex]

Finally the base of the triangle is b = 6 meters
