19% is the smallest because 0.9 as a percentage is 90% and 1/4 is 25%
Answer:
208
Step-by-step explanation:
112+40=152 And that's the rest of them is under 152 so they can't be it so the only option left is 208
I'm not a expert but I'm just trying to help if u need ask someone else to explain but that's the right answer
Answer:
see explanation
Step-by-step explanation:
The perimeter is the sum of the 3 sides, that is
perimeter = 8 + 12 + 17 = 37 cm
To use Heron's formula for area (A)
A =
where a, b and c are the lengths of sides and s the semi perimeter
s = 37 ÷ 2 = 18.5
let a = 8, b = 12 and c = 17, then
A =
=
= ≈ 43.52 cm² ( to 2 dec. places )
B.) 9 cm, 14 cm, 22 cm
It would make an obtuse triangle, and by using the triangle calculator trick or ways you would have to find the area of the triangle, but it would get to confusing...
But also the simplest way or elementary would be
A.) 21 cm, 7 cm 7 cm
I messed up my self I'm am truly sorry but,
I hoped this helped!! <33
