D- dimes
N-nickels
D+N=80
10d+5n=660
N=80-d
10d+5(80-d)=660
10d+400-5d=660
5d=660-400
5d=260
260 divided by 5 is 52

52 dimes and 28 nickels

SVETLANKA909090 [29]

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
