The width is half the length: The perimeter is twice the length plus twice the width. If the perimeter is 3 times the length, twice the width must be the length.
Perimeter = 2(length + width) → width = perimeter ÷ 2 - length length = 1 foot → width = 70 ft ÷ 2 - 1 ft = 34 ft; length = 2 feet → width = 70 ft ÷ 2 - 2 ft = 33 ft.

Assuming the area is rectangular, the area is width * length = 2*1 = 1 square unit.
32.6 (rounded to 1 dp.) Method; Area = length x width Rearranging ... Length = Area / width Length = 228/7 = 32.6
