Ratio 6 : 7 : 8 and ita perimeter is
210 find its area​

Answer 1

Answer

Ratio=6+7+8=21

210 divided by 10 2113.26 sq cm ans please mark the answer as the brainliest and verified

Answer 2

6x+7x+8x=420

21x=420

x=20

so,

6x=120

7x=140

8x=160

now,

Semi perimeter(S)=(120+140+160)/2

=210

a=210-120=90

b=210-140=70

c=210-160=50

area of triangle =

s×a+b×c×
