**Answer:**

x = 39.1

**Step-by-step explanation:**

<u>Points to remember</u>

Mean of a data set is given by

Mean = (sum of data set)/Total number of data

**<u>To find the value of x</u>**

It is given a data set

31.7, 42.8, 26.4, x

Mean = 35

Sum of data set = 31.7 + 42.8 + 26.4 + x = 100.9 + x

(100.9 + x)/4 = 35

100.9 + x = 35 * 4 = 140

x = 140 - 100.9 = 39.1

Therefore** x = 39.1**

**Answer:**

**Base of quilt is 8 inch.**

**Step-by-step explanation:**

Refer to the attachment.

Given that pattern on the quilt is right angle triangle. Consider ΔABC as right angle triangle where ∠ABC=90°.

Given that area of triangle is 24 in² and height is 6 inch that is, AB = 6 inch.

To find the base use **formula for area of right angle triangle.**

Substituting the values,

Simplifying,

Multiplying both sides by ,

Simplifying,

Dividing the numbers,

**Therefore, length of base of each quilt piece is 8 inch.**
