Question

The length of a rectangular fam is 15 inches, and the width of the frame is 8 inches. What

is the length of a diagonal of this frame in inches?
Record your answer below. Just the number.

Answer 1

Answer: 17 inches

Explanation:

The formula for finding the length of a diagonal in a rectangle is
`d=√(w^2+l^2)`

Where

d is the diagonal

w is the width (8 for this)

l is the length (15 for this)

Sub these values into the equation

`d=√(w^2+l^2)\\d=√((8)^2+(15)^2)`

Solve

`d=√((8)^2+(15)^2)\\d=√(64+225)\\d=√(289)\\d=17`
