Answer: Length = l

Width = w

2l + 2w = 80cm

l+w = 40cm

l = w+4

w+4 + w = 40cm

2w + 4 = 40cm

2w = 36cm

w = 18cm

l = 22cm

Answer:

L = 22, W= 18

Step-by-step explanation:

You can use an equation to solve this. Since the length is 4 more than the width, you can use L = W + 4. (L = Length, W = Width). I personally like to draw a diagram to figure out the total sides. We can add up all the sides, using our equations and adding common factors. We know the perimeter is 80 cm, so we can equal it to this. Solve for W. And finally subsitute for L.

Step-by-step explanation:

Given

Red: 150

White: 450

Green: 225

Blue: 375

First, we nee the total number of chairs

Total = 150 + 450 + 225 + 375

Total = 1200

Probability of getting red is then calculated as thus;

P(Red) = Red/Total

P(Red) = 150/1200

P(Red) = 0.125
