Nicolae is installing an L-shaped desk and his new home office. The table top is shown. What is the surface area of the desk? If it is 1 inch thick the height is 40 the length is 35 and the width is 22.
To determine the surface area of the L-shaped desk, we need to first break it down into two rectangles. The first rectangle's dimensions are 40 (length) x 22 (width), and the second rectangle's dimensions are 35 (length) x 22 (width).
Surface area of rectangle 1:
A = l*w
A = 40*22
A = 880 square inches
Surface area of rectangle 2:
A = l*w
A = 35*22
A = 770 square inches
Now add the two areas together to get the total surface area of the desk.
Total Surface Area = 880 + 770
Total Surface Area = 1650 square inches.
The surface area of the desk is 1650 square inches.
