What is the perimeter of this rectangle?
a.) 2(x2 − x1) + 2(y2 − y1)
b.) (x2 − x1)(y2 − y1)
c.)sqrt 2(y2-y1)(x2-x1)
d.)4sqrt (y2-y1)^2(x2-x1)^2
e.)4(y2 − x1)(x2 − y1)

The perimeter of the rectangle is given by

A is the correct option.

Step-by-step explanation:

Distance formula of two points is given by

Using the distance formula,

Length of the rectangle is given by

Width of the rectangle is given by

Hence, the perimeter of the rectangle is given by

A is the correct option.

find out the value of b

step-by-step explanation:

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
