The formula for surface area of a right triangle is A = (b • h)/2 where b is base and h is height. Example 1: A right triangle has a base of 6 feet and a height of 5 feet. Find its surface area. A = (b • h) / 2 A = (6 • 5) / 2 A= 15 feet^2 The area is 15 feet^2 Example 2: A right triangle has a surface area of 21 inches^2 and a base that measures 6 inches. Find its height. A = (b • h ...
If the area of a square is 225 cm2, what is perimeter? How do you find the perimeter and area of a square with side 6 1/2 in? The length of a rectangle is 3 times its width.
The surface area will be the sum of the rectangular base and the #4# triangles, in which there are #2# pairs of congruent triangles. Area of the Rectangular Base. The base simply has an area of #lw#, since it's a rectangle. #=>lw# Area of Front and Back Triangles. The area of a triangle is found through the formula #A=1/2("base")("height")#.
Please see below: There are many different formulas to find the areas of different shapes. Here are a couple shapes and examples: " " " " " " " " " " " " " " RECTANGLES: Rectangle area is ALWAYS: color(red)"width" xx color(red)"height" Say you have a rectangle with a width of 4 and a height of 8 what is the area? "width" xx "height" 4 xx 8 32 The area is 32 "un"^2.
10 The area of any triangle is given by 1/2*b*h where b is the base and h is the hieght. Therefore the area here is 1/2*5*4 = 10
Surface Area: 168 sq.cm. Volume: 120 cu.cm. Here is the prism as I believe it has been described: The hypotenuse length of 10 is calculated based on the Pythagorean Theorem: sqrt(6^2+8^2) Since we were asked to use a perimeter construct in calculating the surface area, we might note that the vertical surface area is: "perimeter of right-triangular base" xx "prism height" =24xx5 =120 The total ...
A solid is formed by a pyramid mounted on a cube, the base coinciding with cube's upper face. Side of cube is #16 cm# and the apothem of the pyramid is #17 cm#. Calculate: the total surface area, the volume and mass knowing is made wood #0.65 g/(cm^3)#?
Heron's formula allows you to evaluate the area of a triangle knowing the length of its three sides. The area #A# of a triangle with sides of lengths #a, b# and #c# is given by: #A=sqrt(sp×(sp-a)×(sp-b)×(sp-c))# Where #sp# is the semiperimeter: #sp=(a+b+c)/2# For example; consider the triangle: The area of this triangle is #A=(base×height)/2#
A = 128 or answer C Surface area is the area of all the surfaces that comprise a single form. In a square pyramid we have five faces, 4 triangles and 1 square. So to determine surface area we need to take the areas of the triangles and square and add them all up. The square's area is relatively simple: A = s^2 A = 8^2 = 64 But now let's observe the triangles, a triangle's area is: A = 1/2bh So ...
To find the area of an equilateral triangle, you need to calculate the length of half the side length and substitute it into the Pythagorean theorem to find the height. You could also substitute it into sin60^@, cos30^@, tan30^@, or tan60^@ to find the height. After finding your height, substitute your values for base and height into the formula for area of a triangle to find the area ...
