hartnn (hartnn):

know how to find the area of rectangle and circle ?

OpenStudy (anonymous):

kinda like what do i divide?

hartnn (hartnn):

this : \(P(event) = \dfrac{Area ~ of ~Rectangle- Area ~of~circle}{Area ~of~ Rectangle}\)

OpenStudy (anonymous):

so divide those or how?

hartnn (hartnn):

first find those areas!

hartnn (hartnn):

Area of rectangle = length* breadth Area of circle = pi * radius^2

OpenStudy (anonymous):

can you please show me?

hartnn (hartnn):

length of rect = 1+1.4 breadth = 0.8 find the area...

OpenStudy (anonymous):

i got 0.26

hartnn (hartnn):

for what ? Area of rect = 2.4*0.8

hartnn (hartnn):

Area of circle = pi *0.4^2

hartnn (hartnn):

then use the probability formula i gave
