Answer 1

photo is 4th and 5th answer is infinite no.of lines

3) Perimeter of equilateral triangle=60m

Let side be x

Perimeter=side+side+side

60=x+x+x

60=3x

x=60/3

x=20

side=20m

Area of equilateral triangle=√3/4X sideX side

=√3/4X 20 X 20

=√3X5 X 20

=1.732X 5 X 20

=173.2m square

i know only these
