Question

the two sides of area of triangle are in the ratio 2:3 and its third side is 5 cm if the perimeter is 15 cm what is the area​

Answer 1

Answer:

Perimeter = Sum of all sides .

Let a, b , c be sides of triangle

Two sides are in ratio 2:3

Therefore let the sides be 2x and 3x.

Third side is 5 cm.

Step-by-step explanation:

Perimeter = a +b +c

15 cm = 2x +3x + 5 cm

10 cm = 5x

2cm =x.

Sides are 2x = 4 cm and 3x = 6cm
