5 x 3 = 15
30 x 3 = 90
15+90=105
so that person paid $105 for that day
10c-15+3-8c-6+5c
7c-18 i think so
Answer:
Since length is three times, hence it is 6 inches.
let the width be x.
then, length= 3x
perimeter= 16 inches.
perimeter of a rectangle = 2( L+B)
2(3x+x)=16.
3x+x= 16÷2
4x= 8
x= 2
since length=3x
hence, 3×2= 6 inches
