Answer:
the answer is 15.15 I am sorry if I am wrong
Answer:
Step-by-step explanation:
Remark
Let x by the multiplying factor to make up 190 m.
2x + 5x + 3x = 190
10x = 190
x = 190/10
x = 19
The longest side is 5x
The longest side = 5 * 19 = 95
Area=l*b=l*(l-2)=80(given)
so, l^2 - 2l =80
l^2 - 2l - 80=0
l=10 or -8
l=10,b=10-2=8
perimeter=2(l+b)=2(18)=36
Answer:
multiply by 10 on both sides
that is to get rid of the denominator
A cube with side length 1 unit is called a unit cube
