The area of a triangle = (base * height) / 2. So here, the area = 12 * 7 / 2 = 84/2 = 42 cm2.
Area of a triangle = 1/2 * Base * Height = 1/2 * 12 * 6.5 = 39 cm2
Area = 12 sqyds
Multiply the base area by the height, and you have the volume.
Area of a triangle = (1/2) x (base) x (height) Can you handle it from there ?
what is the volume if the base area is 32 and the height is 6
The answer is 90 cm2.
The area of a triangle = (base * height) / 2. So here, the area = 12 * 7 / 2 = 84/2 = 42 cm2.
Area of a triangle = 1/2 * Base * Height = 1/2 * 12 * 6.5 = 39 cm2

The area of any triangle is found by multiplying 0.5 x base x perpendicular height (the height of the triangle that is located at a right angle to the base). So for your dimensions, Area = 0.5 x 12 x 6.5 = 39 cm2
1809.56 cm2
The area of a triangle is (1/2) x base x height. The height is perpendicular to the base. In this case, you can take the 10 cm as the base, and calculate the height with Pythagoras' formula. If you split the base in half now you have two 5-12-13 right triangles, so the height is 12 cm and the area is (1/2)*(10cm)*(12cm) = 60 cm2
9 cm x 9 cm x 12 cm is an isosceles triangle with base 12 and height = sqrt(81-36) cm = sqrt(45) cm So area = 1/2 * base * height = 1/2 * 12 * sqrt(45) = 40.25 cm2
Area = length * height. A = 20cm * 12cm A = 240 cm2
Area = 0.5*Base*Height So Base = 2*Area/Height = 2*114/12 = 19 metres.
The base is a square, so since it's area is 25 cm2 it's sides are 5 cm each in length. Thus, the rectangular sides of the prism have an area of 5x12 or 60 cm2. The total surface area is the sum of the 4 rectangular sides at 60 cm2 and the two square faces at 25 cm2.4*60 + 2*25 = 240 + 50 = 290 cm2
