Answer:
A) Perimeter = 9.6 inches
Area = 5.76 inches ^2
B) Perimeter = 57.6 mm
Area = 207.37 mm^2
Step-by-step explanation:
The perimeter and the area of the object in the scale drawing.
Perimeter = 2.4 x 4 = 9.6 inches
Area = 2.4 × 2.4 = 5.76 inches ^2
Then find the perimeter and area of the actual object.
If 1 inch = 6mm, and we have 2.4inches, then we need to multiply: 2.4 × 6 = 14.4
So each side of the square is 14.4 mm long
The perimeter of a square is 4 equal sides, so you will need to multiply 14.4 and 4
14.4×4 = 57.6mm
The area of a square is the length times its width. So that means to find the area, you will need to multiply 14.4 and 14.4 together.
14.4 × 14.4 = 207.36mm^2
