If the area a of a triangle is 45 m2 (square meters) and the altitude h is 15 m, what's the base b?

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;

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;

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

b = 90/15 = 6

Therefore, the base of the triangle is 6 m

Step-by-step explanation:

The area of a triangle is

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

In this case we have a triangle with area

and with height:

So the base of the triangle is:

Finally the base of the triangle is b = 6 meters

there is no grid

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.
