Each of the equal sides of an isosceles triangle is 25 m and base 30m, so find the area. |
|
Answer» ANSWER: The FORMULA for the area of a triangle is A=12⋅b⋅h When the height of an isosceles triangle is drawn to the base it bisects the base. Therefore x=y=15 . Since we have two SIDES of a right triangle we can use the Pythagorean Theorem to find the height. 25² = h² + 15² h² = 625 − 225 = 400 h = 20m A=1/2×30×20 = 300m² Hope it helps! Plz. MARK it as the brainiest. |
