mike is building a new deck in his backyard with the dimensions shown in the diagram. he needs to determine how many
square feet of lumber needs to be purchased. find the total area of the deck.
a)25 ft2
b)50 ft2
c)7512
d) 125 f2

D) 125 ft^2

Step-by-step explanation:

We wil accept the shape as a rectangle to ease things up,

We find the area of rectangle by multiplying height × width

15×10 = 150

since it's not a complete rectangle we subtract 5×5 = 25 from 150

Therefore the area of the deck is 125 ft^2
