Answer:
110,190,240
Step-by-step explanation:
11x+19x+24x=54x
54x=540
x=540/5
x=10
110,190,240
Answer:
hi!!!!
here is your answer!!!!!
Step-by-step explanation:
perimeter of triangle = 540
Let the ratio be 11x 19x and 24xcm
So,
11x +19x+24x =540
54x =540 cm
X =10 cm
11x =11×10=110
19x= 19×10 =190
24x=24 × 10 =240
540
------ = 270

area of triangle =√s[s-a] [s-b] s-c]
= √270[270-110] [270-140] [270-240]
=√270 [160] [80] [30]
=√3×10×9×[2×8×10] [8×10] [2×10]
= 10×10√3×3×3×2×2×2×2×2×2×2×3
=100×3×3×2×2×2√2
=100×72√2
=7200√2
therefore the area is 7200√2
