1/5=10
There are 10 baseball cards
1/10=5
There are 5 football card's
50-10-5=35
There are 35 basketball card's
35-10=25
Gerry has 25 more basketball card's than baseball card's
Perimeter (P) of a square = 4s ; where s is the length of a side
1 yd = 4s
yd = s
Area (A) of a square = s²
= (
)²
Now, convert from yard to foot to inch:
()² x (
)² x (
)²
= (3 x 3 x 12 x 12) ÷ (4 x 4)
= 81 in²
Geometry
You need to find the area of the square first.
8x8=64un^2
Then you must find the area for the four triangles.
8x6=42un^2
42un^2/2=21un^2
Then multiply this by four to find the area of all the triangles.
21un^2x4=84un^2
Then add the areas of the triangles and squares.
84un^2+64un^2=148un^2
