Answer:

Step-by-step explanation:

This will be solved using distance formula between two coordinates.

The distance formula between two coordinates is given as;

d =

Point T has coordinate of T(80,20)

Distance to Point U(20,60) is;

TU =

TU =

TU ≈ 72 Units

Distance From Point U(20,60) to Point V(110,85);

UV =

UV =

UV ≈ 93 units

I didn't bother to calculate TV because we are looking for shortest distance for the trip and by inspection if he goes from T to V first before Point U, it will be a longer journey.

Thus, shortest distance = TU + UV

shortest distance = 72 + 93 = 165 units

Using it's formula, the surface area of the figure is:

A. S=2332 m²

<h3>What is the surface area of a rectangular prism?</h3>

The surface area of a rectangular prism of dimensions l, w and h is given by:

S = 2(lw + lh + wh)

In this problem, the dimensions are:

35m, 9m, 16m

Hence the surface area of the rectangular prism is:

S = 2(35 x 9 + 35 x 16 + 16 x 9) = 2038 m².

<h3>What is the surface area of a cube?</h3>

The surface area of a cube of side length l is given by:

S = 6l².

In this problem, we have that l = 7 m, hence the surface area is:

S = 6 x 7² = 294 m².

<h3>What is the total surface area?</h3>


The total surface area is the sum of the surface areas, hence:

T = 2038 m² + 294 m² = 2332 m².

Which means that option A is correct.
