Can't see the figure, but the basic way to solve this problem is to use the formula for volume of a pyramid which is (length * width * height )/3. Slant height is just the square root of ((length/2)2 + height2) recognizing that there is a right triangle there. Since slant height increased by 4 cm when its height increased by 2cm, you know that the length/2 term had to increase by the square root of 12 (22+root(12)2) = 42=16. From there you can figure out the rest pretty readily.
She needs 48 yards of border trims
The first step is to determine the total sum of border trims needed in feet
45 feet + 51 feet + 48 feet = 144 feet
The next step is to convert feet to yards
1 foot = 0.333333 yards
144 x 0.333333 = 48 yards
