Help me pls I don’t get it

Answer 1

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
`cm^2`

Answer: 8
`cm^2`
