Math Problem Statement
Jawad’s bedroom has one wall that does not have a door or window.
A rectangle with length 4 and 2-thirds yards and width 3 and 1-half yards.
A. Complete the statements to estimate the area of the wall.
312 rounds to
. 423 rounds to Choose... . The area of the wall is about
square yards.
B. Find the actual area of the wall.
Solution
Let's break down this problem step by step.
Part A: Estimating the Area
We have a rectangle with the following dimensions:
- Length: yards
- Width: yards
To estimate the area, we'll round the dimensions to simpler whole numbers:
- Length: (since is closer to 5)
- Width: (since is closer to 3)
Now, we estimate the area:
For the rounding part:
- rounds to 5.
- rounds to 3.
Thus, the estimated area is about 15 square yards.
Part B: Actual Area of the Wall
To find the exact area, multiply the actual dimensions of the rectangle:
- Length: yards
- Width: yards
Now, calculate the area:
Final Answers:
- A. Estimated area of the wall is about 15 square yards.
- B. The actual area of the wall is square yards.
