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
