• A. $200sqm$
• B. $180sqm$
• C. $170sqm$
• D. $190sqm$

Answer 1

The correct option is A $200sqm$

Solution:
Length of one of the sections of the backyard $=16m$
Width of the section $=8m$
Area of the section $=16\times 8=128sqm$

Estimated area $=130sqm$

Length of the other section of the backyard $=12m$
Width of the section $=6m$
Area of the section $=12\times 6=72sqm$

Estimated area $=70sqm$
Total area of the backyard $=130+70=200sqm$
