Answer 2

Answer:

the length of rectangle is 21 inches

Step-by-step explanation:

the sides of rectangle make right angle with each other and length breath and diagonal together make a triangle

so, let length be x

20^2 +x^2 = 29^2. (by Pythagoras theorem)

400 +x^2= 841

x^2 = 441

x = √441

x= 21

therefore, lenght is 21 inches
