Step-by-step explanation:

The original price of a sweater = $42

The sweater is on sale for 30% off, so the new price of the sweater is

$\$42-0.3\cdot \$42=\$29.40$

The sales tax is 5%, so Kensington has to pay for the new sweater

$\$29.40+0.05\cdot \$29.40=\$30.87$

Since it's a square, all sides are equal
therefore,
3x - 5 = x + 1
2x = 6
x = 3

sub x into AD, which is 3x-5
= 3(3) - 5
= 9 - 5
= 4

therefore AD is 4 units
