Question

a triangular lot is 120 ft on one side and has a property line of length 800 ft. find the area of the lot in acres. (figure not drawn to scale)
area ≈ □ acre(s)
(round to the nearest hundredth as needed.)

Explanation:

Step1: Calculate area in square - feet

The area formula for a right - triangle is $A=\frac{1}{2}bh$. Here, the base $b = 800$ ft and the height $h = 120$ ft.
$A=\frac{1}{2}\times800\times120$
$A = 48000$ square feet.

Step2: Convert square - feet to acres

We know that 1 acre = 43560 square feet.
Let $x$ be the area in acres. Then $x=\frac{48000}{43560}$.
$x\approx1.10$ acres.

Answer:

$1.10$
