worty [1.4K]

Answer:

186 beats per minute

Step-by-step explanation:

The maximum heart rate (r ) in beats per minute is modeled by the equation :

r = 220 - a ...(1)

Where

a is age of the person in years

If Sanchez age is, a = 34 years

Put a = 34 in equation (1)

What is the figure formed?What is the area of the figure?

$\large \green{ \underline{ \blue{ \boxed{\bf{ \red{Solution-}}}}}}$

The given points lie on graph as per the order given in the attachment.

Which shape?

As the points lie 2 units apart from their adjacent sides. It can be a square or rhombus.

The opposite pairs of sides are also parallel to each other. The adjacent sides of the figure formed are also perpendicular to each other.

<u>Hence! the figure formed is a square.</u>

What is the area?

$\large{\sf{ \longmapsto Area_{(square)} = s \times s}}$

$\large{\sf{ \longmapsto Area_{(square)} = {s}^{2} }}$

$\large{\sf{ \longmapsto Area_{(square)} = {(2)}^{2} }}$

$\large{\sf{ \longmapsto Area_{(square)} = 4 \: sq. \: units}}$
