Answer:
340 ft^2
Step-by-step explanation:
The length of one side is 1/4 of the perimeter, so is 10 ft.
The area of the base is the square of the length of the side:
base area = (10 ft)^2 = 100 ft^2
__
The lateral area is the area of four triangles, each with a base of 10 ft and a height of 12 ft.
lateral area = 4(1/2)(10 ft)(12 ft) = 240 ft^2
__
The total surface area is the sum of the base area and the lateral area:
surface area = base area + lateral area
surface area = (100 ft^2) +(240 ft^2) = 340 ft^2
My vector calculator* tells me
100∠130° +25∠90° = 122.2∠122.3°
The plane's ground speed is 122.2 km/h and its course is 122.3° from north.
