Answer:To find out the Area of a scalene triangle whose three sides are given, first find out the half perimeter
s = (a+b+c)/2
where a, b, and c are the length of the three sides of a triangle
s = (35 + 45 + 50) / 2
= 130 / 2
= 65 cm
Area of scalene triangle is given by
A = sqrt (s (s - a) (s - b) (s - c))
= sqrt (65 * (65 - 35) ( 65 - 45) (65 - 50))
= sqrt (65 * 30 * 20 * 15)
= sqrt (585000)
= 764.853 sq cm

Answer: $817.35
Step-by-step explanation:
150x4 = 600
600+217.35 = 817.35
Yeah its gonna be 18 square feet in wide and length and the area is gonna be 36 square feet
1) 900/4=225
225*5=1125
900:1125
2) 1000/3=333.33
333.33*7=<span>2333
1,000:2333
</span>
3) 200/3= 66.66
66.66*5=333
200:333
4) 600/7=<span>85.7
</span>85.7*8= <span>686
</span>600:686
13) 120/7=<span>17.1
</span><span>17.1*3=51
</span><span>17.1*2=34
</span>120:51:34
14)450/5= 90
90*6= 540
90*7= 620
450:540:620
15) 550/5=110
110*8= 880
110*90= 990
110:880:990
16) 13.86/3= 4.62
4.62*7= 32
4.62*11= 51
13.86:32:51
