Answer:
Length = 3 cm
Width = 1 cm
Step-by-step explanation:
Let the length of rectangle be l and width of rectangle be w.
According to problem,
l = 3w {Length of rectangle is equal to triple the width}
And Perimeter,P = 8 cm
Since, P = 2 ( l + w )
or 8 = 2( l + w)
Plug l =3w in the above perimeter equation.
We get:
8 = 2( 3w + w)
8 = 2(4w)
8 = 8w
or w = 1 cm
Then length ,l = 3w =3 * 1 = 3 cm
Hence length of rectangle is 3cm and width of rectangle is 1cm.
461 because you take 506-45 to find x(the unknown number)
Answer:
The last one is the correct answer.
Step-by-step explanation:
Answer:
11.x>50
12.y is greater than or equal to 8
15. z<8
Step-by-step explanation:
Answer:
$29,750
Step-by-step explanation:
Area (pavement) = 2 x 3.5(50 + 35)
= 7 x 85
= 595 sq. m.
Cost
= 400 per 8. sq. m.
= 50 per sq. m.
=> 595 x 50
=> $29.750
