You have a large collection of 1 × 1 squares and 1 × 2 dominoes. You want to arrange these to make a 1 × 15 strip. How many ways can you do this? Start by collecting data. How many length 1 × 1 strips can you make? How many 1 × 2 strips? How many 1 × 3 strips? And so on. How are the 1 × 3 and 1 × 4 strips related to the 1 × 5 strips? How many 1 × 15 strips can you make? What if I asked you to find the number of 1 × 1000 strips? Would the method you used to calculate the number fo 1 × 15 strips be helpful?

Step-by-step explanation:

To solve this strip question, there’s a need to draw a strip diagram (which is a rectangular mathematical presentation that is used to show arithmetical relationships and may also be used for fractions representation or solve problems that involves operations.)

Kindly check the attached images below to see the step by step explanations to the above question

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
