How many square feet of outdoor carpet will we need for this hole?

For this you would want to break this fgure up with familar shapes. You can do two triangles and one big rectangle.

First triangle:

(3)(2)(1/2)= 3 feet squared

Second Triangle:

(3)(4)(1/2)= 6 feet squared

Rectangle:

(11)(3)= 33 feet squared

Now you add:

33+3+6= 42 feet squared

So, for this hole you will need 42 feet squared of outdoor carpet

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

9 x 8 divided by (5-3)=36
