Answer 1

First Picture :

The Approximate Distance between Points D(-4 ,-1) and E(4 ,-3) can be found by using Distance formula.

⇒ Distance = $\sqrt{(-4 - 4)^2 + (-1 + 3)^2} = \sqrt{64 + 4} = \sqrt{68} = 8.25 units$

D is the Answer

Second Picture :

$\sqrt{10} units$

(3,4) and (2,1)

(-2,3) and (1,2)

(-4,-2) and (-3,1)

Remaining Belong to $\sqrt{29}$

Third Picture :

The Approximate Distance between Points T(1 ,-1) and E(2 ,-4) can be found by using Distance formula.

⇒ Distance = $\sqrt{(1 - 2)^2 + (-1 + 4)^2} = \sqrt{1 + 9} = \sqrt{10} = 3.16 units$

C is the Answer

Fourth Picture :

The Approximate Length of side XY = 3.16 units

The Approximate Length of side YZ = 4 units

The Approximate Length of side ZX = 4.24 units

The Approximate Perimeter of Triangle XYZ = 11.4 units

Fifth Picture :

The Approximate Length of side LM is = 6.4 units and the Approximate Perimeter of the Triangle LMN is 22.8 units.

C is the Answer
