Answer: 27cm²

Step-by-step explanation:

lets take the width as x and length as 3x( since length is 3 times the width)…

Perimeter of the rectangle is 24 cm( 2*(l+b))= 2×(3x+x):24

2×4x=24

8x=24

X( width): 24/8=3cm

Length= 3x: 3*3=9cm

Area of the rectangle: ( l*w)= 9×3: 27cm²

marishachu [46]

Answer:

Step-by-step explanation:

In the first pattern, there were 6 sticks

In the second pattern, there were 10 sticks.

In the third pattern, there were 14 sticks.

Based on the pattern, we see that each time, 4 more sticks are added and that the initial amount of stick is 6.

Thus: the equation for how many sticks there would be in pattern n is:

# of sticks in pattern n = 6 + 4n

Hope that helps!
