The following octagon is formed by removing four congruent triangles from a rectangle. What is the area of the rectangle? class=

Verified Answer :

Area= length times width. 10×6 is 60. Answer is 60 cm^2

Answer:

\(A=60 cm^{2}\)

Step-by-step explanation:

The area of a rectangle is defined as

\(A=l \times w\)

Where \(l\) is the length and \(w\) is the width.

If you observe the given graph, you will find that the dimensions are

\(l=2+6+2=10cm\)

\(w=2+2+2=6cm\)

So, replacing these dimensions we have

\(A=10cm \times 6cm\\A=60 cm^{2}\)

Therefore, the right answer is the last choice, \(A=60 cm^{2}\)
