In the given figure, LMNO and GHJK are rectangles where GH = 1/2 LM and HJ = 1/2 MN. What fraction of the region is bounded by LMNO that is not shaded? (figure not drawn to scale)
A. 1/4
B. 1/3
C. 1/2
D. 3/4​

Answer 1

3/4

Explanation:

To answer this question we must first calculate the area of GHJK:

• A= GH*HJ
• A= (LM/2)* (MN/2)
• A= LM*MN/4
• LM/MN is the area of LMNO
• So the area of LMNO is 4 times the area of GHJK
• A is the area of LMNO and S the area of GHJK
• S= A/4
• A-S= A-A/4 = 3A/4
• so the area that is not shaded is 3/4
