Which measure is closest to the perimeter of an equilateral triangle with an area of 24 square feet?
It works out as 22.335 feet rounded to three decimal places
What is the area rounded to the nearest tenth of a square inch of an equilateral triangle that has a perimeter of 24 inches?
Area of equilateral triangle: 0.5*8*8*sin(60 degrees) = 27.7 square inches rounded
Is a equals 6cm find the area of the equilateral triangle round the answer to one decimal place?
For an equilateral triangle with side length a, area = (a²√3)/4, which for a= 6cm is 15.6 cm² [rounded to 1 decimal place]
What is the area of an equilateral triangle whose perimeter is 22.5 cm?
It is: 0.5*7.5 square*(sin 60 degrees) = 24.357 square cm rounded up to 3 d.p.
If a 6 cm find the area of the equilateral triangle. Round the answer to one decimal place.?
To find the area of an equilateral triangle, you can use the formula: area = (sqrt(3)/4) * s^2 where s is the length of one side of the triangle. If the length of one side of the triangle is 6 cm, the area of the triangle is: area = (sqrt(3)/4) * 6^2 = (sqrt(3)/4) * 36 = (3.46/4) * 36 = 13.83 * 36 = 498.68 Rounded to one decimal place, the area of the triangle is approximately 499 cm^2.
What is the perimeter and area of an equilateral triangle with a side of 8?
Perimeter of equilateral triangle: 24 units Area of equilateral triangle: 27.713 square units rounded to three decimal places

What is the area of an equilateral triangle when its perimeter is 22.5 cm?
Area = 0.5*7.52*sin(60 degrees) = 24.357 square cm rounded to 3 dp.
What is the area of an equilateral triangle whose perimeter is 22.5 cm?
It is: 0.5*7.5 square*(sin 60 degrees) = 24.357 square cm rounded up to 3 d.p.
What is the length of the altitude of an equilateral triangle when sides are 20 in length?
Using Pythagoras' theorem its height works out as 17.321 inches rounded to 3 decimal places
What is the perimeter and area of a triangle when a length between its angles of 55 degrees and 48 degrees is 5cm?
Its 3rd angle is 77 degrees and by using the sine formula for a triangle its 2 other sides are 4.2cm and 3.8cm both rounded to 1 decimal place which means it has a perimeter of 13cm and its area works out as 7.81 square cm rounded to 2 decimal places.

What is the perimeter of a triangle when its shortest side is 3.6cm with angles of 37.25 degrees and 48.4 degrees?
Using the sine rule a/A = b/B = c/C the perimeter of the triangle works out as 13.98 cm rounded to two decimal places
Triangle ABC is an isosceles right triangle with angle an equal to 90 degrees Find the perimeter if AB equals 19 Round answer to 2 decimal places?
There are two equal sides of 19 units in the right angled triangle. To find the third side use Pythagoras' theorem: 192+192 = 722. The square root of 722 = 26.87005769 Perimeter of triangle = 19+19+26.87005769 = 64.87005769 Therefore perimeter of triangle rounded to 2 decimal places = 64.87 units.
