How do you find the area of a triangular field?
The area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle.
How do you find the area of two angles?
To calculate the area of a triangle given one side and two angles, solve for another side using the Law of Sines, then find the area with the formula: area = 1/2 × b × c × sin(A).
What is the area of the field?
To calculate the area of a field with right angles at the comers, multiply the length by the width of the field. Example: a field is 100 metres long and 100 metres wide; its area is 100 x 100 = 10000 square metres (m2). A square metre is a square measuring 1 metre In length and 1 metre in width.
What are lengths of sides of a triangle whose perimeter is 540 m and sides are in the ratio 25 17 12?
Answer Expert Verified. So, the sides are 25x , 17x , 12x where x is any positive no. So, the sides are 250m , 170m & 120m.
How do I find height of a triangle?
How to Calculate the Height of a Triangle. Triangle height, also referred to as its altitude, can be solved using a simple formula using the length of the base and the area. Thus, the height or altitude of a triangle h is equal to 2 times the area T divided by the length of base b.
How do you find the angle of a triangle with two angles?
The key to finding the missing angle measure of a triangle is to remember that the sum of the interior angles of any triangle is always 180°. If you know 2 angles then you can subtract their sum from 180° to find the measure of the 3rd angle.
What is the formula to calculate the area of a triangle?
Now, if any two sides and the angle between them are given, then the formulas to calculate the area of a triangle is given by: Area (∆ABC) = ½ bc sin A Area (∆ABC) = ½ ab sin C Area (∆ABC) = ½ ca sin B
How to find the area of a triangle using Heron’s formula?
The first step is to find the semi perimeter of a triangle by adding all the three sides of a triangle and dividing it by 2. The next step is that, apply the semi-perimeter of triangle value in the main formula called “Heron’s Formula” to find the area of a triangle.
How do you find the area of an isosceles triangle?
Area of an Isosceles Triangle = A = ½ (base × height) Perimeter of a Triangle The perimeter of a triangle is the distance covered around the triangle and is calculated by adding all the three sides of a triangle. The perimeter of a triangle = P = (a + b + c) units
What is the area of a triangle with base b and height?
To be noted, the base and height of the triangle are perpendicular to each other. The unit of area is measured in square units (m2, cm2). Example: What is the area of a triangle with base b = 3 cm and height h = 4 cm? Area of a Triangle, A = 1/2 × b × h = 1/2 × 4 cm × 3 cm = 2 cm × 3 cm = 6 cm 2.
