What is the area of the triangle?

A = 48 in²

Step-by-step explanation:

The area (A) of the triangle is calculated as

A = bh ( b is the base and h the perpendicular height )

Here b = 24 and h = 4 , then

A = × 24 × 4 = 12 × 4 = 48 in²

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
