A gift shop uses two sizes of boxes for presents. These boxes have exactly the same shape. The smaller box is 24 cm long, and the larger box is 28 cm long. If 828 cm^2 of wrapping paper is needed to cover the smaller box, how much wrapping paper is needed to cover the larger box?

b

step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
