Answer:
20 cm² & 80 cm²
Step-by-step explanation:
Ratio of areas = (ratio of sides)²
Ratio of sides: 2/4 = ½
Ratio of areas: (½)² = ¼
Areas are:
⅕(100) = 20
⅘(100) = 80
<span>The correct answer is option A. i.e parallelogram. In a parallelogram, the diagonals bisect each other i.e. one diagonal cuts the other diagonal into equal parts. So, The diagonals of a parallelogram bisect each other. And all the other options, rhombus, rectangle and square are also parallelograms only.</span>
using trigonometry:-
cos of angle ? = 7/16
so ? = arccos 7/16 = 64.06 degrees
The other angle is 90 - 64.06 = 25.94 degrees
