Find the area of the triangle whose base is 12 m and height is 15m.

The formula be A = 1/2 x 12 x 12
the answer be 90

Right.

To find the area of a triangle, you can use the formula A = 1/2 x base x height, where A represents the area, the base is the length of the triangle's base, and the height is the perpendicular distance from the base to the top vertex of the triangle.

In this case, the base of the triangle is given as 12 m and the height is given as 15 m. Plugging these values into the formula, we have:

A = 1/2 x 12 x 15

To simplify the expression, we can perform the multiplication:

A = 1/2 x 180

To calculate 1/2 x 180, we divide 180 by 2:

A = 90

Therefore, the area of the triangle with a base of 12 m and a height of 15 m is 90 square meters.
