The question are in the png

Kindly check explanation

Step-by-step explanation:

1) shape = square

Side length = 6.5 in

Area of square = (side length)²

Area = 6.5^2 = 42.25 in²

Perimeter of square = 4 * side length = 4 * 6.5 = 26 in

2.) shape = rectangle

Dimension = 1.1 by 2.8m

Area of rectangle = Length * width = 1.1 * 2.8 = 3.08 m²

Perimeter of rectangle = 2(length + Width)

Perimeter = 2(1.1 + 2.8) = 2(3.9) = 7.8 m

3.) triangle

Base = 4.5 ; height = 6.5 ; hypotenus = 7.9 cm

Area = 0.5bh = 0.5 * 4.5 * 6.5 = 14.625 cm²

Perimeter = (4.5 + 6.5 + 7.9) cm = 18.9 cm
