Question

Significant Figures: A rectangular garden measures 15 m long and 13.70 m wide. What is the length of a diagonal from one corner of the garden to the other?

Answer 1

The diagonal of rectangular garden is 19.90 m

Explanation:

We are given the following in the question:

Measure of rectangular garden:

Length, l = 15 m

Width, w = 13.70 m

We have to find the length of diagonal of rectangle.

The diagonal of rectangle, d will be given by Pythagoras theorem as it is the hypotenuse of the right angles triangle.

Thus, we can write,

`d = √(l^2 + w^2)`

Putting values, we get,

`d = √((15)^2+(13.07)^2)\\d = √(225 +170.8249)\\d \approx 19.90`

Thus, the diagonal of rectangle is 19.90 m
