The area of a triangle with legs that are 15 m, 25 m, and 20 m is
Further Explanation;
Area Area is a measure of how much space is occupied by a given shape.
Area of a substance is determined by the type of shape in question.
For example;
Area of a rectangle is given by; Length multiplied by width
Area of a circle = πr². where r is the radius of a circle,
Area of a square = S², Where s is the side of the square.etc.
Area of a triangle The area of a triangle is given based on the type of the triangle in question.
Right triangle.
The area of a right triangle is given by;
= 1/2 x base x height
Scalene triangleIt is a triangle that with sides and angles that are not equal.Area of a scalene triangle depends on the features of the triangle given.
For example;
Sine FormulaArea of a triangle = 1/2 ab sin θ, when given two sides of the triangle and the angle between them
Heron's formulaArea of a triangle =
when given all the sides of the triangle.
where
In this case we are given, a = 15 m, b = 25 m, c = 20 m
Therefore, we use the Heron's formula;
Area=
Therefore;
Area =
=
=
