A tent is in the shape of an equilateral triangle. The triangular
base has a length of 4 feet and a height of 3.5 feet. The
rectangular sides and bottom of the tent have the dimensions
of 6 feet by 4 feet. The surface area of the tent is
square feet.

Respuesta :

The surface area of the tent is  86 ft²

Surface area of a triangular prism

  • SA = area of base + area of top + area of the three sides

Therefore,

The base and top are triangular.

Therefore,

area of base = 1 / 2 bh = 1 / 2 × 4 × 3.5 = 7 ft²

area of the tope = 7 ft²

Therefore, the other three rectangular sides are calculated as follows:

area = 6 × 4 = 24 ft²

area = 6 × 4 = 24 ft²

area = 6 × 4 = 24 ft²

Therefore,

Surface area = 7 + 7 + 24 + 24 + 24 = 86 ft²
