The surface area of the right triangular prism is 270 sq ft
<h3>Total surface ara of the prism</h3>
The total surface area of the prism is the sum of all the area of its faces
For the two triangles
A = 2(0.5bh)
A = bh
A = 7 * 12 = 84 sq.ft
For the two rectangles
A = 2lw
A = 2(6*12)
A = 2 * 72 = 144 sq.ft
For the third triangle;
Area 6ft * 7ft
Area = 42 sq.feet
Taking the sum of the areas
TSA = 84 + 144 + 42
TSA = 270 sq ft
Hence the surface area of the right triangular prism is 270 sq ft

Answer:10
Step-by-step explanation:
Divide 12.75 by 1.25
you get 10.2
She can cut 10 strings but has 0.2 string leftover
12.25x2=24.50 (width x2)
24.50-1=23.50 (length)
Area= LxW
=23.50x12.25
=287.88 feet
