Find the area of an equilateral triangle that has a perimeter of 21 inches. round the answer to one decimal?
Area of equilateral triangle: 0.5*7*7*sin(60 degrees) = 21.2 square inches
How do you find the area of a triangle with base 21 inche and height 8 inches?
area = 1/2*base*perpendicular height =1/2*21*8 =84 square inches
The height of a triangle is four times the length of the base find the base and height of the triangle if the base is 18 square inches?
18 square inches is probably the area of the triangle, not the length of the base. The length of the base would be measured in inches (a unit of length), not square inches (a unit of area). So area = 1 / 2 * base * height = 18 square inches (given) height = 4 * base (given) 1 / 2 * base * 4 * base = 18 square inches 2 * base * base = 18 square inches base * base = 9 square inches base = 3 inches height = 4 * base = 4 * 3 inches = 12 inches Checking our work: height is 4 times the base (12 = 4 * 3) area is 18 (1/2 * 12 * 3).
The height of a triangle is 18 inches Find the length of the base if the area of the triangle is 63 square inches?
Since the formula for the area of a triangle is: A = .5 x h x b just go 63 = .5 x b x 18 then 63 = 9b 7 = b
What is the area of a square if the sides are 6 inches long?
To find the area of a square, you multiply the length of one side by itself. In this case, if the sides are 6 inches long, the area would be 6 inches * 6 inches = 36 square inches.
Find the area L 16 in H 14 in in a triangle?
Area of the triangle: 0.5*16*14 = 112 square inches
If an equilateral triangle measures 9 inches on each side what is the perimeter?
Area of a triangle = 1/2*base*height Use Pythagoras to find the height which is 7.794228634 inches Area = 1/2*9*7.794228634 = 35.07402885 square inches Answer: 35 square inches to the nearest square inch.
Find the area of an equilateral triangle that has a perimeter of 21 inches. round the answer to one decimal?
Area of equilateral triangle: 0.5*7*7*sin(60 degrees) = 21.2 square inches
The altitude of a triangle is 5 inches less than its base. the area of the triangle is 42 square inches . find its base and altitude?
The dimensions are: altitude 12 inches and base 7 inches Check: 0.5*12*7 = 42 square inches
Find the area of an equilateral triangle with the given measurement six inch side?
The formula to calculate the area of a triangle is (base/2) x height... therefore the are of the triangle in this case is 18 square inches
Explain how can you calculate the area of a right angled triangle with a base of III inches and a hypotenuse of V inches giving an exact answer in Roman numerals?
First rearrange Pythagoras' Theorem equation to find the height of the triangle in order to find the area: Height2 = hypotenuse2-base2. Height2 = 52-32. Height2 = 16. Height after square rooting both sides of the equation = 4. Area of a triangle = base*height/2 = 3*4/2 = 6 square inches. Therefore the area of a right angled triangle with dimensions in inches of III by IV by V is VI square inches. David Gambell, Merseyside, England.
What is the height of the triangle with an area of 70 square inches and a base of 7 inches?
The formula for finding the area of a triangle is: Area = 1/2*height*base in square units. Therfore substituting the values into the formula we have: 70 = 1/2*height*7 Rearranging the formula to find the height gives us: height = 70*2/7 = 20 inches. Therefore the height of the triangle is 20 inches.
What is the area in square graph units of a triangle?
The area of a triangle can be calculated using the formula A = 1/2 * base * height, where the base is the length of the triangle's base and the height is the perpendicular distance from the base to the opposite vertex. The area is typically measured in square units, such as square inches, square centimeters, or square meters. To find the area in square graph units, you would need to know the specific dimensions of the triangle in the graph.
