Answer:
12.3
Step-by-step explanation:
A^2 + B^2 = C^2
11^2 + 4.5^2 = C^2
132 + 20.25 = C^2
152.25 = C^2
Square root of 152.25 = 12.3
Answer:

Answer:
11.4 metres
Step-by-step explanation:
Use Pythagoras theorem for a right-angled triangle
a^2 + b^2 = c^2
if you cut the rectangle in half, it will become a right angled triangle.
a and b are two sides of the rectangle, while c is the diagonal or hypothenuse
so 9^2 + 7^2 = c^2
81 + 49 = c^2
c^ 2 = 130
square root 130 = c
you should get approximately 11.4 metres
