Question

A teacher asks her students to design a game board for a class project. The dimensions of the boards created by four students are shown below. Angela length: 20 cm width: 21 cm diagonal: 29 cm Bradley length: 9 in. width: 9 in. diagonal: 9 in. Carlton length: 25 cm width: 30 cm diagonal: 35 cm Della length: 10 in. width: 12 in. diagonal: 15 in. Whose game board could be a rectangle? Angela Bradley Carlton Della

Answer 1

Answer:ANGELA

Step-by-step explanation:

As the length ,width and diagonal of a rectangle form a right triangle

length^2+width^2=diagonal^2

thus , the game board with dimensions of a right triangle will be a rectangle.

out of the above only

20^2+21^2=29^2

thus angela's game board is rectangle

Answer 2

Answer: It's A or Angela

Step-by-step explanation: The diagonal of a rectangle formula is: √(l² + w²) but you have to compare the sides so taking square root on both sides: √(29²) = √( 20² + 21²) = (29) = (29) . So the equation is equal thus the answer is A or Angela.
