Answer:
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
