Difficulty: EasyPerimeter and Area of 2D Figures

A painter is marking a new parallelogram-shaped crosswalk on a street. The base of the parallelogram is 4545 feet long, and the perpendicular height across the street is 2020 feet. What is the total area of the crosswalk, in square feet?

Answer: 900 sq ft

Answer

900
The area of a parallelogram is calculated by multiplying its base by its perpendicular height. Given a base of 4545 feet and a height of 2020 feet, the area is 45×20=90045 \times 20 = 900 square feet.

Step-by-Step Solution

1
Identify the relevant formula
A=b×hA = b \times h
The area of a parallelogram is the product of its base and perpendicular height.
2
Substitute the given values into the formula
A=45×20A = 45 \times 20
The base (bb) is given as 4545 feet and the height (hh) is 2020 feet.
3
Calculate the final area
900900
Multiplying 4545 by 2020 gives 900900.
