Answer 2

Answer:

Area = 0.9682458366 sq m

Step-by-step explanation:

This is an isosceles triangle

If we take 1 m side as base

The perpendicular from opposite vertex will divide

the base

using pythagoras theorem we get

h = sqareroot of ( 4 - 0.25)

= sqareroot of 3.75

= 1.9364916731 m

Area = h × b ÷2

= 1.9364916731 × 1 ÷ 2

= 0.9682458366 sq m

OR

_____________

Area =√p(p−a) (p−b) (p−c)

where a,b,c are length of the sides

and p is half the perimeter, or 

(a+b+c )÷2

p= 1+2+2=5/2 = 2.5 m

_____________________

Area =√ 2.5 ( 2.5- 1) ( 2.5- 2) ( 2.5- 2)

_______________

Area =√ 2.5 ( 1.5) ( 0.5-) ( 0.5)

=0.9682458366 sq cm
