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
Area of the rectangle is 144cm. The sides of a square with the same ares is 12cm.
12 x 9 = 108 square centimeters
To find the area of a rectangle, you multiply the length by the width. In this case, the width is 7cm and the length is 9cm. So, the area would be 7cm x 9cm = 63 square centimeters.

The formula for finding the area of a trapezoid is:A = (1/2) (b1 + b2 ) h
Area = 108cm2 Width = 12cm Length = 9cm
Area of the rectangle is 144cm. The sides of a square with the same ares is 12cm.
To determine if these three sides form a right triangle, we can use the Pythagorean theorem. In a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. In this case, we have 6^2 + 9^2 = 36 + 81 = 117 and 12^2 = 144. Since 117 is not equal to 144, these three sides (6cm, 9cm, 12cm) do not form a right triangle.
The formula for the surface area is 2lw + 2hl +2hw. So, 2(9*12)+2(9*12) +2(9*9)=?
53.5 square cm to 1 d.p. Use the cosine rule to find an angle. Then use: Area = 1/2*a*b*sin C
A right triangle has a hypotenuse of 12cm and a leg that is 9cm the other leg would be 7.94. This is a math problem.
15 cm Solved through Pythagoras' theorem.
The area of a rectangle of sides 9cm and 10cm is:9cm x 10cm = 90cm2This is equivalent to 0.009m2
12 x 9 = 108 square centimeters
