Question

if the perimeter of a triangle is60 CM, then what is its area? ​

Answer 1

Hey mate...

Step-by-Perimeter = 60cm

Step-by-Perimeter = 60cm 1 side = 60/3 = 20 cm

Step-by-Perimeter = 60cm 1 side = 60/3 = 20 cm√s(s-a)(s-b)(s-c)s(s−a)(s−b)(s−c)

Step-by-Perimeter = 60cm 1 side = 60/3 = 20 cm√s(s-a)(s-b)(s-c)s(s−a)(s−b)(s−c) s = 30

Step-by-Perimeter = 60cm 1 side = 60/3 = 20 cm√s(s-a)(s-b)(s-c)s(s−a)(s−b)(s−c) s = 30 √30(30-20)(30-20)(30-20)

Step-by-Perimeter = 60cm 1 side = 60/3 = 20 cm√s(s-a)(s-b)(s-c)s(s−a)(s−b)(s−c) s = 30 √30(30-20)(30-20)(30-20)=√30×10×10×10=√30000cm² = 100√3 cm²

Step-by-Perimeter = 60cm 1 side = 60/3 = 20 cm√s(s-a)(s-b)(s-c)s(s−a)(s−b)(s−c) s = 30 √30(30-20)(30-20)(30-20)=√30×10×10×10=√30000cm² = 100√3 cm²Mark as Brainliest
