Jackie plans to place a rectangular piece of art inside a rectangular frame. She considers a piece of art that is 0.5 meters lon

tamaranim1 [39]

Answer:

The art is rectangular because $(0.5) ^2 + (1.2) ^2 = (1.3) ^2$

(0.5) squared + (1.2) squared = (1.3) squared

Step-by-step explanation:

Given that the piece of art is rectangular in shape.

Length of piece of art = 0.5 meters

Width of piece of art = 1.2 meters

Kindly refer to the attached image in the answer area.

Two adjacent sides of a rectangle are given, the diagonal value can be found by using Pythagorean Theorem.

According to Pythagorean theorem:

$\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}$

Here, Hypotenuse will be the diagonal of the rectangle.

Base and Perpendicular will be the two adjacent sides.

Therefore,

$Diagonal^2 = 0.5^2+0.12^2\\\Rightarrow Diagonal^2 = 0.25+1.44\\\Rightarrow Diagonal = \sqrt{1.69}\\\Rightarrow Diagonal = 1.3\ m$

Therefore, the answer is:

The art is rectangular because $(0.5) ^2 + (1.2) ^2 = (1.3) ^2$

(0.5) squared + (1.2) squared = (1.3) squared
