Answer:
Explanation:
Step 1: Find the width of larger rectangle
Since these are similar rectangles, ratio of length to width will be same in two rectangles. Ratio of length to width of smaller rectangle is 2:1. Let’s assume width of larger rectangle is x cm.
(2/1) = (4/x)
2x = 4
x=2
Therefore, the width of larger rectangle will be 2 cm.
Step 2: Calculate area of larger rectangle
Area of rectangle = length . width
= 4 . 2 = 8

Answer: 8
