What is the surface area of this design?<br> A.150in2<br> B.197in2<br> C.210in2<br> D.127in2
ANEK [815]

Answer:

197 in ^2 (answer B of the list)

Step-by-step explanation:

Notice that this figure has a total of 6 faces, four of which are rectangles (whose area is calculated as "base times height") and two trapezoids (whose area is (B+b)H/2 ).

The total surface area is therefore the addition of these six areas:

Rectangles:

5 in x 5 in = 25 in^2

5 in x 5 in = 25 in^2

5 in x 6.4 in = 32 in^2

9 in x 5 in = 45 in^2

Trapezoids:

Two of equal dimensions: B = 9 in, b = 5 in, H = 5 in

2 * (9 in + 5 in) 5 in /2 = 70 in^2

Which gives a total of  (25 + 25 + 32+45 + 70) in^2 = 197 in^2

This agrees with answer B of he provided list.

Dvinal [7]

Answer:

The border will be 18.6 inches wide

Step-by-step explanation:

<em>Let the width be w</em>

<em>The length = 43 inches</em>

<em>Total wood = 800 square inches</em>

Formula for area of rectangle = length x width

<em>800 = 43 x w</em>

<em>w = 800/43</em>

w = 18.6 inches

Therefore, the border will be 18.6 inches wide.
