Area is 36cm2
Fist lets start by reviewing what the area of a pyramid is. Volume of a pyramid (with a rectangular base) is the Area of the Base x Height x 1/3. Where the 1/3 comes in I don't know but that's the equation. So we have a rectangle with the sides measuring 9cm x 12cm. The area of a rectangle is S1 * S2 so we have an area of 9cm*12cm=108cm2. We are given the height (altitude) as 12 cm so now that we know the area of the base, and the height we can find the volume. V= 108cm2 * 12cm *1/3 V= 1296cm3*1/3 V= 432cm3
The area of a triangle is calculated using the formula: Area = 0.5 * base * height. In this case, the base is 18cm and the height is 12cm. Plugging these values into the formula, we get Area = 0.5 * 18cm * 12cm = 108 square centimeters. Therefore, the area of the triangle is 108 square centimeters.

Area of a triangle = 1/2 (Base x Height) Example: Width 13cm, Height 5cm, Base 12cm then; Area=1/2(12cm x 5cm) Area=6cm x 5cm Area=30cm2
Oh, what a happy little triangle we have here! To find the area, we simply multiply the base (12cm) by the height (6cm) and then divide by 2. So, the area of this lovely triangle would be 36 square centimeters. Just remember, there are no mistakes in art or math, only happy little accidents!
The area of triangle is : 18.0

Area = base x altitude /2 so base = 2 x area/altitude = 64/6 = 10 & 2/3 cm.
