Answer
The total area of the squares = 29 square cm
The triangle is not a right-angled triangle
Step-by-step explanation:
We are given three squares
The first square has a length of 4cm
The second square has a length of 3cm
The third square has a length of 2cm
Part A
Total area = Area of square 1 + Area of square 2 + Area of square 3
Area of a square = l^2
Where l is the length of the square
Area of a square 1 = 4^2
Area of a square = 16 square cm
Area of square 2 = 3^2
Area of square 2 = 9 square cm
Area of square 3 = 2^2
Area of square 3 = 4 square cm
Total area of the square = 16 + 9 + 4
The total area of the square = 29 square cm
Hence, the total square of the figure is 29 square cm
