Area of the triangle: 0.5*6*4 = 12 square inches
4 inches Area= 1/2(base)(height)
4"
It is 22 in2. Multiply 4 by 11 and divide by 2.
area_parallelogram = base x height = 20 in x 4 in = 80 square inches
To find out the area of a triangle the formula is half base X height Therefore you go 3 (half of 6-the base) times 4 (the height) giving you the answer of... = 12
area of triangle = half (base*height) i.e. 1/2*(4*4)= 8 square inch.

4 inches Area= 1/2(base)(height)
Area of triangle: 0.5*12*4 = 24 square inches
18 square inches is probably the area of the triangle, not the length of the base. The length of the base would be measured in inches (a unit of length), not square inches (a unit of area). So area = 1 / 2 * base * height = 18 square inches (given) height = 4 * base (given) 1 / 2 * base * 4 * base = 18 square inches 2 * base * base = 18 square inches base * base = 9 square inches base = 3 inches height = 4 * base = 4 * 3 inches = 12 inches Checking our work: height is 4 times the base (12 = 4 * 3) area is 18 (1/2 * 12 * 3).
