The formula for area of a triangle is base times height divided by 2,
A=BxH/2
So if you're referring to "20 cm and 13 cm" as the base and height,
13x20=260, 260/2=130, so the answer is 130 square cm.
:D
30 sq cm ((12 x 5)/2)
1/2*13*11 = 71.5 square cm
Area = pi*132 = 530.9291585 or 531 square cm
750 sq cm
29cm times 13cm= 377cm squared :)
30 square cm because it's a right angle triangle
Oh, what a happy little triangle we have here! To find the area, we can use Heron's formula. First, we find the semi-perimeter by adding all three sides and dividing by 2. Then we plug the values into the formula: Area = √(s(s-a)(s-b)(s-c)), where s is the semi-perimeter, a, b, and c are the sides. Happy painting!
13cm*13cm =169 square cm.
30 sq cm ((12 x 5)/2)
1/2*13*11 = 71.5 square cm
I don't think there is enough information to answer the question, first of all, is it a right triangle? Second, is the the 13cm the hypotenuse. Assuming that 13cm is the hypotenuse, and the triangle is a right triangle, the equation would be 49+x^2=169
The area is 60cm2
The area of triangle is : 100.0
