Question

I really need help please on this assignment i would appreciate it and will give brainliest!!!

Answer 1

1) let the width of the rectangle X

given :

l = 3x

b = X

perimeter of rectangle = 36cm

2(l+b) = 36

2(3x + X ) = 36

4x = 36 / 2

X = 18 /4

X= 4.5 cm

hence, b = 4.5 cm and l = 3 ×4.5 cm = 13.5cm

2)

For Nancy:A=425+25n

For Seamus:a =875-15n

when their amounts are equal

425+25n=875-15n

40n=875-425

40n=450

n=11.25

They will both have the same amount 1/4 of theway into the 12th week
