Can someone plsss help me :((

No

Step-by-step explanation:

equation is y=2x+3

The point we have is (15,29)

i.e. x=15 and y=29

if we put x=15 in the equation we should get the value of y=29

y=2(15)+3

=30-3

=27

Here, we didn't get y=29 instead we got y=27

So the point (15,29) doesn't follow that equation

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk
