lets do it the way i used to do it
12x+17x+25x=54x
perimeter=side+side+side (in a triangle)
540 =54x
540/54=x
10=x
lets take base as 12x ,i.e.,120
and height as 25x,i.e.,250(both are in cms)
area=b*h
area =1/2(b*h)
area=1/2(120*250)
area=1/2(30000)\
area=1/2*30000
area=15000
answer is 15000

but it is not a right angle triangle

Let 12,17, and 25 be 12x, 17x and 25x
12x+17x+25x=540cm
=> 54x=540cm
=> x=10cm
Therefore, the sides are:
120cm
170cm
250cm For area, find semi-perimeter (s) That is, P/2 =270cm A= Square root of [s(s-a)(s-b)(s-c)]
12x+17x+25x=540cm
=> 54x=540cm
=> x=10cm
Therefore, the sides are:
120cm
170cm
250cm For area, find semi-perimeter (s) That is, P/2 =270cm A= Square root of [s(s-a)(s-b)(s-c)]
Area is 9000 square cm. please rate my answer as the brainliest if it was helpful.
