17.5 sq. cm
17.5cm squared
Square root of 45.
The area of a triangle is (1/2) x base x height. The height is perpendicular to the base. In this case, you can take the 10 cm as the base, and calculate the height with Pythagoras' formula. If you split the base in half now you have two 5-12-13 right triangles, so the height is 12 cm and the area is (1/2)*(10cm)*(12cm) = 60 cm2
Area = 1/2 * base * height Area = 1/2(10 cm)(15 cm) = 75 cm2 ======
The area of every triangle is 1/2 of the product of (length of its base times its height).You can probably take it from there.
Area = 1/2*base*height = 0.825 sq cm. The fact that the triangle is isosceles is irrelevant: it makes no difference to its area.
35/2 cm² 0r 17.5 cm² area = 0.5 x base x height
Area of isosceles triangle: 0.5*5*7 = 17.5 square cm
17.5cm squared
Area = 1/2*5*7 = 17.5 square cm
1/2*5*7 = 17.5 square cm
1/2*5*7 = 17.5 square cm
assuming its an isosceles triangle, then its 16 cm high
Area = Base*Height so Base = Area/Height = 720/15 = 48 cm
9 cm x 9 cm x 12 cm is an isosceles triangle with base 12 and height = sqrt(81-36) cm = sqrt(45) cm So area = 1/2 * base * height = 1/2 * 12 * sqrt(45) = 40.25 cm2
