A rectangle is eight inches and diagonal is ten

inches. What's the width of the rectangle?

Answer: Its width is 6inches.

Step-by-step explanation:

The given information can be used to construct a right angled triangle. Now applying the Pythagoras theorem,

10^2 = W^2 + 8^2

where w represents the width.

100 = w^2 + 64

100 - 64 = w^2

36 = w^2

find the square root of both sides,

6 = w

Therefore, w = 6 inches

Thus the width of the rectangle is 6 inches.
