So we know that the area of only the pool is 198 ft^2. To find the area of the entire yard, multiply length times width so:
Area of yard = 22 ft x 30 ft
Area of yard = 660 ft^2
Now subtract the pool area from the yard area:
660 - 198 = 462
So the area of only the yard is 462 ft^2
Hope this helps!!
Answer:
35 [$]
Step-by-step explanation:
1) if Peter's sum is p and Jacky's is j, then the ratio 5:2 in the condition can be written j/p=5/2;
2) the phrase 'after Jacky gave 15 dolls to Peter, they have an equal number of dolls' can be written as j-15=p;
3) using the two above it is possible to make up the system of two equations:
