Question 1to 4 tomorrow I have board exam fast plz

Answer 1

Answer:1-d,2-c,3-c,4-c.

Step-by-step explanation:

Side of equilateral triangle is √3/4a2 so 4- c.

1.) side=6cm

√3/4(62)=

√3/4*36

So 9√3 1-d

2.)h=9cm

√3/2*side=9

√3/2*a=9

a=(9*2)√3

a=6√3 so 2-d

3.)area of square =s*s

s*s=3136

s=56cm so 3-d.

Hope you understand tq
