a trinagle jas two angles: 9cm and 7cmWhat is the area in square centimeter(1 point)
cm2
The area of a triangle can be calculated using the formula:
Area = 1/2 * base * height
Since we know the base and height of the triangle (9cm and 7cm), we can substitute these values into the formula:
Area = 1/2 * 9cm * 7cm
Area = 1/2 * 63cm
Area = 31.5cm2
Therefore, the area of the triangle is 31.5 square centimeters.
