all the answers are good. the area of a triangle is always 1/2 the area of a rectangle with the same length for the base and height. so the rectangle would have an area of 3*9, or 27 and the triangle would have an area 1/2 that, or 13.5.

formula of area of a triangle is 1/2 x base x height..so,
= 1/2 x base x height
= 1/2 x 3 x 9
= 1/2 x 27
= 27/2
= 13.5

The area is 13 and a half.
To work out the area of a triangle you multiply the length of the base by the height and divide by 2.
Base = 3. Height = 9
3 x 9 = 27
27 divided by 2 = 13 and a half.

A= 1/2bh
A= 1/2(3)(9)
A= 1/2 (27)
A= 13.5

The formula is 1/2 bh. So---3 x 9 = 27 and 27/2= 13.5 Therefore 13.5 square units is the area

base x height div. by 2
3 x 9 = 27
Div. by 2 =13.5

1/2 base x height,
1.5 x 9 = 13.5

A = .5 * b * h
A = .5 * 3 * 9 = 13.5
The area is 13.5 square units

A= bh * 1/2 --> (3 * 9) / 2 --> 13.5
