Step-by-step explanation:
The ratio of sides of the lengths of rectangles is 3:4.
- Now since the scale is constant. So the scale ratio of area will be square of the side ratio .
<u>T</u><u>hat </u><u>is </u><u>:</u><u>-</u><u> </u>
→ Ratio of Area = ( 3 : 4)²
→ Ratio of Area = (3/4)²
→ Ratio of Area = 9/16
→ Ratio of Area = 9:16
<h3>
Hence the ratio of areas is 9:16 .</h3>
