Question

How do you find the diagonal of a rectangle whose length is 12 in. and whose width is 9 in?

Answer 1

12×9 =area of rectangle
d=1/2×108

Answer 2

Answer:

One inch is 2.5 cm.

Since the length of the rectangle and width is given, we can use Pythagoras theorem to solve this.

In the given figure, consider triangle BCD with BC = 9 in and DC = 12 in.

using pythagoras' theorem,

BD² = BC² + DC²

Solve it and take the root of the obtained value, which will be 15 inches.

Multiply with 2.5 to convert to cm
