Two similar hexagons have their perimeters in the ratio 5 : 7. If the smaller hexagon has an area of 75 cm2, what is the area of the larger hexagon?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 147 cm2.
Area ratio = (Side ratio)2
Area ratio = (5/7)2 = 25/49
Larger area = 75 × (49/25) = 147 cm2
