Answer:
hey mate here is ur ans..
Step-by-step explanation:
The total area covered by an isosceles triangle is known as its area. For an isosceles triangle, the area can be easily calculated if the height (i.e. the altitude) and the base are known. By multiplying the height with the base and dividing it by 2 gives the areas of the isosceles triangles.
An isosceles triangle is one which has at least two sides of equal length. This property is equivalent to two angles of the triangle being equal. An isosceles triangle, therefore, has both two equal sides and two equal angles. The name derives from the Greek iso (same) and Skelos (leg). An equilateral triangle is a special case of the isosceles triangle where all the three sides and angles of the triangle are equal.
Isosceles Triangle
Because the isosceles triangle has two equal side lengths and two equal angles where those sides meet the third line, it is a symmetrical shape. If a perpendicular line is drawn from the point of intersection of two equal sides to the base of the unequal side, two right-angle triangles are generated.
Area of Isosceles Triangle Formula
The area of an isosceles triangle is given by the following formula:
Area = ½ × base × height
Also,
Perimeter of Isosceles Triangle P = 2a + b
Altitude of Isosceles Triangle h = √(a2 − b2/4)
List of Formulas to Find Isosceles Triangle Area
Formulas to Find Area of Isosceles Triangle
Using base and height A = ½ × b × h
Using all 3 sides A = ½[√(a2 − b2 ⁄4) × b]
Using length of 2 sides and angle between them A = ½ × b × c × sin(α)
Using 2 angles and length between them A = [c2×sin(β)×sin(α)/ 2×sin(2π−α−β)]
Area formula for isosceles right triangle A = ½ × a2
hope it helps u mate

Answer:
please followme
Step-by-step explanation:
In an isosceles triangle , altitude is bisect to base . therefore altitude =/((side length of equal side )2-(base2)2 =
/b2-a24) now area of isiceles .
