# Find the area of 5.8 and 8 in a triangle?

23.2.

Step 1: 5.8*8=46.4

Step 2: 46.4 ÷ 2=23.2 So that is your answer.

### What is the area of a right triangle that is 4cm by 8cm?

The area of a right-angle triangle is half of the area of a rectangle 8cm x 4cm. Find the rectangle area and divide by half to find the area of the right-angle triangle. Therefore: 8 x 4 / 2 = 16cm2 * * * * * The above answer assumes that the two given lengths are the shorter legs of the triangle. It is, however, possible that these are the hypotenuse and one leg. In…

### If a right triangle has a hypotenuse of 15 and a leg length of 8 What is the area of the triangle?

In order to find the area, you need to know the two leg lengths. The hypotenuse won't tell you the area, but it does help you find the other leg length though the Pythagorean theorem A2 + B2 = C2, where A and B are the legs and C is the hypotenuse. You have: 82 + B2 = 152 64 + B2 = 225 B2 = 161 B = sqrt(161) which is approximately 12.69 The…

### How do you find the area of an equilateral triangle with a perimeter of 24in?

In an equilateral triangle, all of the sides have the same length and all of the angles are the same. Since the total of all three angles in any triangle always equals 180 degrees, each angle of an equilateral triangle is one third of 180 degrees, which is 60 degrees. Likewise, the length of each side is one third of the entire perimeter, or 8 in. The area of a triangle is the product of…

### If a triangle has a area of 16 and a base of 4 what is the height of the triangle?

Best Answer - The formula for the area of a triangle is A = (bh)/2. We need to manipulate the formula to find out height. 1. Multiply both sides by 2. 2A = bh 2. Divide both sides by B (2A)/b = h So, you can use this formula now. [(2)(16)]/4 = h 32/4 = h h = 8 units. To check the answer, find the area of the triangle, if the basre is 4…

### How do you find out the missing piece to an area model?

Usually the two triangle pieces have different pitches. So by swapping them it makes the total triangle area different. Red triangle pitch: atan(3/8) = 20.56 deg Blue triangle pitch: atan(2/5) = 21.80 deg When the blue is on the top, the total triangle bends inwards slightly, and when its at the bottom, the total bends outwards. Thus changing the area of the triangle and making room for an empty block.

### Which triangle has the greater area triangle A has base 13 m and height 5 m and triangle B has base 9 m and height 8 m?

Triangle B The area of a triangle is the length of the base times the height divided by two. Triangle A has base 13 m and height 5 m so we have (13 * 5) / 2 = 32.5 square meters. Triangle B has base 9 m and height 8 m so we have (9 * 8) /2 = 36 square meters. Therefore Triangle B has the greater area.

### Is it possible to find the dimensions and area of a right angle triangle when given only its hypotenuse which is 8 cm?

No. Additional Information:- Yes providing it's not an isosceles right angle triangle the possible dimensions are:- hypotenuse 8 cm, height 6.4 cm and base 4.8 cm because they comply with Pythagoras' theorem. So the area is:- 1/2*6.4*4.8 = 15.36 square cm Note that if it was an isosceles triangle then the dimensions and area could also be worked out that is why you should have specified in your question the type of triangle.
