Question

choose the correct answer.
a. area = 8 sq. units
b. area = 10 sq. units
c. area = 9 sq. units
d. area = 9 sq. inches

Explanation:

Step1: Count the number of rows and columns

Looking at the figure, the rectangle (or the arrangement of squares) has 1 column (width) and 8 rows (height)? Wait, no, wait. Wait, looking again, maybe it's 1 column and 8? Wait, no, maybe I miscounted. Wait, the figure shows a vertical arrangement of squares. Let's count the number of squares. Let's see, the vertical strip: how many squares? Let's count: from top to bottom, 8? Wait, no, maybe 1 column (width = 1 unit) and 8 rows (height = 8 units)? Wait, no, maybe I made a mistake. Wait, the formula is length × width = area. Wait, the figure is a rectangle made of unit squares. Let's count the number of unit squares. Let's see, the vertical strip: each square is 1 unit. Let's count the number of squares: 8? No, wait, maybe 1 column and 8 rows? Wait, no, maybe the figure is 1 column (width = 1) and 8 height? Wait, no, maybe the correct count is 1 (width) × 8 (height) = 8? But wait, the options: A is 8 sq units. Wait, but let's check again. Wait, maybe I miscounted. Wait, the figure: let's count the squares. The vertical rectangle: how many squares? Let's see, the first square at the top, then 7 more? Wait, no, maybe 8? Wait, 1 (width) × 8 (height) = 8. So area is 1×8=8. So option A is area = 8 sq units.

Wait, but let's confirm. The formula for the area of a rectangle is length × width. If the width is 1 unit (1 square) and the length (height) is 8 units (8 squares), then area is 1×8=8 square units. So the correct option is A.

Step2: Match with the options

Option A says area = 8 sq. units, which matches our calculation.

Answer:

A. area = 8 sq. units
