Answer:
10
Step-by-step explanation:
So we have the expression:
First, evaluate within the absolute value bars. 3 times -4 is -12. Thus:
Now, subtract:
The absolute value of -10 is positive 10. So:
And we're done!
The shape in the figure is constructed from several identical squares. If the side of each square is 1 unit, what is the area an
d the perimeter of the shape?
1 answer:
Answer:
Area = 7 square units
Perimeter = 14 units
Step-by-step explanation:
The shape is made up of 7 identical squares and, we are told the side length of each square is 1 unit.
==>Find area of the shape by calculating the area of 1 square, then multiply by the number of square used in the construction.
Thus, area of 1 square = s² = 1² = 1 square units.
Area of shape = 7 × 1 square units = 7 square units
==>Find the Perimeter of the shape by adding all the lengths of the boundary formed by the square to make up the shape.
(Check attachment to understand how we got the measurement of the boundary)
<em>The perimeter = 1 + 1 + 1 + ½ + ½ + 1 + 1 + 1½ + ½ + 1 + 1 + 4 = 14 units</em>
