Question

A flat patio was built along side a house as shown in the figure above. If all angles are right angles, what is the area of the patio in square feet?

• A. $800$
• B. $875$
• C. $1000$
• D. $1100$
• E. $1125$

Answer 1

The correct option is C $1000$

Area of patio $=$ area $ABCD$ - area $PQRD$

$=$ $(40\times 35)-(20\times 20)$

$=1400-400=1000$ sq. ft
