Answer:
9 units²
Step-by-step explanation:
calculate the area of Δ ABC as
area of rectangle - area of 3 outer right triangles
area of rectangle = 5 × 4 = 20 units²
area of left Δ = × 3 × 3 = 4
units²
area of Δ on right = × 2 × 4 = 4 units²
area of top Δ = × 5 × 1 = 2
units²
Then
area of Δ ABC = 20 - 4 - 4 - 2
= 20 - 11 = 9 units²

Answer:
As square root of 9 can be written in the required form for being a rational number, so it is a rational number
Step-by-step explanation:
First of all we'll define rational numbers.
A number that can be written in the form p/q where p and q are integers and q≠0 is called a rational number.
Now we have to check if is rational or not, we will check if it can be written in the form p/q
As square root of 9 can be written in the required form for being a rational number, so it is a rational number
