Answer:
4/20
Step-by-step explanation:
20 %
Percent means out of 100
20/100
Divide top and bottom by 10
2/10
We want the denominator to be 20 so multiply the top and bottom by 2
4/20
He didn’t multiply the equation by 1/2 in the second part so it threw his whole answer off. Hope this helps

Answer:
12.9 square yards
Step-by-step explanation:
The base is an equilateral triangle, so we can assume that the three faces have the same dimensions. Each of those face triangles has an area of ...
A = 1/2bh
A = 1/2(3 yd)(2 yd) = 3 yd²
The base area is computed using the same formula and the given height:
A = 1/2(3 yd)(2.6 yd) = 3.9 yd²
Then the total surface area is that of the base and the three faces:
SA = (3.9 yd²) + 3(3 yd²) = 12.9 yd² . . . total surface area
