The sum of the lengths that are less than the feet given in their case will be 6.69 feet.
<h3>How to calculate the sum</h3>
Your information is incomplete as the values aren't given. Therefore, assumed lengths will be given in this scenario.
Let's assume that the lengths of the boards that are less than 4 feet long include 3.4 feet, 1.2 feet, and 2.09 feet.
In this case, you'll add the sum together. This will be:
= 3.4 + 1.2 + 2.09
= 6.69 feet

The common difference is -7
Answer:
1,560,000 mm²
Step-by-step explanation:
A= This would make shape A's area <u>480,000</u>.
B= This would make shape B's area <u>180,000</u>.
C= This would make shape C's area <u>300,000</u>.
D= 1000×600 This wouls make D's area <u>600,000</u>.
Now you add up all of the areas;
480,000+180,000+300,000+600,000= 1,560,000 mm²
