Remark

You have to make an assumption here. I know of no other way to do the problem than by making the assumption that 10 * 14 figure is a rectangle. If that is not true, the problem is not solvable.

Step One

Find the length of the shaded area.

The length will be the length of the hypotenuse of a right triangle formed by the two smaller sides = the hypotenuse.

a = 4

b = 12

c =

Length

L = square root (a^2 + b^2)

L = √(4^2 + 12^2)

L = √(16 + 144)

L = √160    =  √(4*4 * 10)

L = 4√(10)

Width

The width is done the same way.

a = 6

b = 2

w = c = ??

w = √(6^2 + 2^2)

w = √(36 + 4)

w = √40

w = √(2 * 2 * 10)

w = 2 √ 10

Area

Area = L * W

Area = 4√10 * 2√10

Area = 8 * 10

Area = 80
