2 less than the difference of u and 3

u - 3 - 2

u - 3 - 2 or (u - 3) - 2

the correct answer is 828.07

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
