An equilateral triangle measures 9 inches on each side its area is?

(81/4)*(sqrt(3))The area of a triangle is expressed by 1/2 bh, where b is the base length of the triangle, and h is the vertical height. In this instance, the base is equal to 9. The height of an equilateral triangle can be found using the Pythagorean theory with a being half the length of one side of the equilateral triangle, h being the height, and c (the hypotenuse) being the length of one side of the equilateral triangle.Thus,a2+h2=c2(9/2)2+h2=(9)2h2=81-(81/4)h=9(sqrt(3))/2So, A=1/2 bh=1/2 (9)(9(sqrt(3))/2)=(81/4)*(sqrt(3))Area = 1/2 * length * heightheight is square root 2(9)2 = square root 2(81)=square root 192 = 13.85640646...1/2 * 13.85640646 * 9 = 62.3538290 est. to 62.3 square inch

What is the surface area of the regular pyramid given 9 and the height is 9?

To calculate the surface area of a regular pyramid, we need the area of the base and the area of the triangular faces. Assuming the base is a square with a side length of 9, the area of the base is (9^2 = 81). The slant height can be calculated using the height of 9 and half the base length (4.5) using the Pythagorean theorem. Finally, the total surface area is the base area plus the area of the four triangular faces.

What is the area of a triangle that is 9cm and 18cm and 9cm?

To find the area of a triangle, you can use the formula A = 1/2 * base * height. In this case, the base is 18 cm and the height is 9 cm. Plugging these values into the formula, we get A = 1/2 * 18 cm * 9 cm = 81 square cm. Therefore, the area of the triangle is 81 square cm.
