A quadrilateral has vertices at (0,1), (3,4), (4,3) and (3,0). Its perimeter can be expressed in the form a\sqrt2+b\sqrt{10} with A and B integers. What is the sum of A and B?

The sum is 6

Step-by-step explanation:

Given

Required

The first step is to name each points, as follows

Next is to calculate the distance between each consecutive point

We'll calculate the distance AB, BC, CD and DA

Distance between points is calculated as thus;

Calculating distance AB

Here,

Expand 18 as 9 * 2

Split surds

Take square root of 9

Calculating distance BC

Here,

Calculating distance CD

Here,

Calculating distance CD

Here,

At this point, the perimeter can then be calculated

From the given parameters;

This implies that;

By comparison;

a = 4 and b = 2

Hence;

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
