The area A of a triangle with base b and height h is given by A=1/2bh. Find the area when b=45m(meters) and h=86m.
Multiply: 86 * 45 = ?
Divide the product by 2.

To find the area of a triangle when its base and height are given, you can use the formula A = (1/2)bh, where A represents the area, b is the length of the base, and h is the height.
In this case, the length of the base (b) is given as 45m and the height (h) as 86m.
To find the area, substitute these values into the formula:
A = (1/2)(45m)(86m)
Now, multiply the base and height:
A = (1/2)(45m * 86m)
Simplify the multiplication:
A = (1/2)(3870m²)
Now, multiply the factor 1/2 by the value:
A = (1/2) * 3870m²
Finally, evaluate the expression:
A = 1935m²
Therefore, the area of the triangle with a base of 45m and a height of 86m is 1935 square meters.
