Question

from a plate of 0.5 metre x 0.5 metre equilateral triangles of side 5cm are cut. how many maximum triangle can be cut of it

Answer 1

Area of plate divided by area of triangle.

Answer 2

let, side of a plate be a

a=o.5 m

in cm, a =50 cm.

let. side of equilateral triangle be h=5cm and altitude be l

l^2=h^2 + (h/2)^2

l^2=25 +25/4

l^2=125/4

l=(5(5)^1/2)/2

area of plate=n(area of equilateral riangle

triangle)
