A slice is made perpendicular to the base of a right rectangular prism, as shown.

What is the area of the resulting two-dimensional cross-section?

168, 280, 140, 20, and 240 are the options given

3212333222555321233322321

Step-by-step explanation:

B. 280

Step-by-step explanation:

The dimensions of the cross sections would be:

Base = 14

Height = 20

Find the area:

14 × 20 = 280

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine
