Question

Joshua has a rectangular work table. The sides of the table are 40 inches by 25 inches. What is the length of the diagonal of the table.

Answer 1

Given:

Dimensions of the rectangular table are 40 inches by 25 inches.

To find:

The length of the diagonal of the table.

Solution:

Diagonal of a rectangle is:

`d=√(l^2+w^2)`

Where, l is the length and w is the width of the rectangle.

Putting
`l=40,w=25` in the above formula, we get

`d=√((40)^2+(25)^2)`

`d=√(1600+625)`

`d=√(2225)`

`d\approx 47.17`

Therefore, the length of the diagonal is about 47.17 inches.
