Question

find the area of floral design whose sides are 12 13 and 5​

Answer 1

Answer:

30 unit^2

Step-by-step explanation:

See, there are two approaches to solve this question.

1. Heron Formula (which is super lengthy, and dont worry if you dont know it)

2. Let's try to see if it is a right triangle, i think that will really make the question easy.

so, by pythagoras theorem.

base^2 + height^2 = hypotenuse ^2

5^2 + 12^2  [ ] 13^2

25 + 144  [ ] 169

169 is indeed = 169

thus, it's a right triangle.

now it is easy, area of right triangle = bh/2 = 5 * 12/2 = 60/2 = 30 unit^2

hope it helps, mark as brainliest if it did
