Answer:
The area of the rectangle is 0.0875 sq ft.
Step-by-step explanation:
Given that,
The length of the rectangle, L = 0.35 feet
The breadth of the rectangle, B = 1/4 feet
We need to find the area of the rectangle. The formula for the area of a rectangle is given by :
A = LB
Put all the values,
So, the area of the rectangle is 0.0875 sq feet.

Answer:
srry what do u mean?
Step-by-step explanation:
The mean is the average. To find this, we add up all the numbers, then divide by the number of numbers there are.
12+23+17+20+14+14+18+16+17+18+18= 187
187/11=17
The mean is 17.
The median is the middle number. To find this, line up all the numbers, smallest to largest.
12, 14, 14, 16, 17, 17, 18, 18, 18, 20, 23
You then cross off numbers from both sides, until you have 1 number remaining.
Your median is 17.
The mode is the number that occurs most frequently.
Your mode is 18.
