Question

Find the perimeter of the following shape: A. 10.8 B. 11 C. 11.4 D. 11.6

Answer 1

Answer:

A: 10.8

Step-by-step explanation:

AD = BC

AB = DC

2AD + 2AB

AD = ±$\sqrt{3^2+1^2}$ ≈ ±3.1622

AD ≈ 3.1622

AB = ±$\sqrt{2^2+1^2}$ ≈ ±2.236

AB ≈ 2.236

2AD + 2AB = 2*3.1622 + 2*2.236 ≈ 10.79 ≈ 10.8
