PLS HELP! Alexis has a rectangular backyard that is 50 yards by 55 yards. She wants to build a
fence that stretches diagonally from one corner to the opposite corner. About how
many yards of fencing will Alexis need? Round to the nearest tenth.

Given:

Alexis has a rectangular backyard that is 50 yards by 55 yards.

She wants to build a fence that stretches diagonally from one corner to the opposite corner.

To find:

The length of the fencing she needs.

Solution:

We have,

Length = 50 yards

Width = 55 yards

We know that, the diagonal of a rectangle is

On further simplification, we get

Therefore, the length of the required fencing is 74.3 yards.

yes

step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
