Question

What is the number of equilateral triangles of side 3 cm that can fit in an equilateral triangle if side 11.2cm

Answer 1

all sides of equilateral triangle is equal
there's third side equal 11.2

Answer 2

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
