Hey mate
Hope it helps you
At first
a=3
area of equilateral triangle= √3/4(side)²
=√3/4(3)²
Now,again
A=11.2cm
Area of equilateral triangle= √3/4(side)²
√3/4(11.2)²
Areaofequilateraltriangle= √3/4 (side)²
= √3/4(11.2)²
Now,
No.of maximum number of equlateral triangles=√3/4×11.2×11.2/√3/43×3
= 11.2×11.2/3×3
=125.44/9
=13.93∼14
Hence, the number of maximum equlateral triangle=13
