Question

area of triangle is 180cm² and the side is in ratio 3:4:5 what is perimeter ?​

Answer 1

Step-by-step explanation:

area = 180

area = 180ratio =3:4:5

area = 180ratio =3:4:5multiply the ratio by x

area = 180ratio =3:4:5multiply the ratio by x3x, 4x,5x

now substitute the 3 sides in the formula with the value of area and we can find x

now substitute the 3 sides in the formula with the value of area and we can find xnow substitute the value of x for the three numbers so we can get the sides

perimeter = side 1 + side 2+ side 3
