Question

How to find sides of a triangle if the area and perimeter are given. ​

Answer 1

Step-by-step explanation:

perimeter =base of triangle

area of triangle = ½ ×base ×height

e.g

if area is 30 sq.cm and base is 12 cm ( perimeter)

then find height

ans: area of triangle = ½ ×base×height

30= ½ × 12×height

30×2 ÷ 1×12

60÷ 12

=5 cm

so height = 5cm

now we have height and base now separate triangles and it becomes right angled triangle

now by pythagoras theorem

1. (hypotenuse)² = ( base)² + (height)²
2. (h)²= ( 12)² + (5)²
3. (h)²= 144 + 25
4. (h)² = 169
5. ( hypotenuse)² = (13)².....(now cancel square both side )
6. hypotenuse = 13

so side =13 ...

sides of triangle are 12 ,13 , and 13
