Answer:

The length of AB is $\sqrt{74}\ units$

Step-by-step explanation:

we know that

The formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

$A(2,-6)\\B(7,1)$

substitute

$d=\sqrt{(1+6)^{2}+(7-2)^{2}}$

$d=\sqrt{(7)^{2}+(5)^{2}}$

$d=\sqrt{49+25}$

$AB=\sqrt{74}\ units$

A rectangular board is 1300 millimeters long and 800 millimeters wide. What is the area of the board in square meters?

hichkok12 [17]

Multiply 1300 mm by 800 mm to get 1040000 mm. Then convert this to meters. 1 meter=1000 mm. Therefore, 1040000 mm is the same as 1040 meters.
