Step-by-step explanation:

The length along the x-axis is 5 - (-1) = 6. The length along the y-axis is 3 - (-1) = 4. The perimeter of this rectangle can be calculated as

$P = 2x + 2y = 2(6) + 2(4) = 20\:\text{units}$

The area of the rectangle can be calculated as

$A = xy = (6)(4) = 24\:\text{units}^2$

See the attached figure to better understand the problem

we know that

tan 29°=AC/CB--------> CB=AC/tan 29°
AC=110 ft
CB--------> <span>how far the man is from the helicopter landing pad
</span>so
CB=AC/tan 29°----------> CB=110/ tan 29°----------> CB=198.45 ft

the answer is
the man is 198.45 ft from the helicopter landing pad
