Step-by-step explanation:

just add all the area of all square

1² + 4² + 7² + 8² + 9² + 10² +14² +15² + 18² =

Answer:

1056

Step-by-step explanation:

Find the area of each square and add them to find the area of the rectangle

The area of a square = side * side

The areas are:

1*1= 1

4*4 = 16

7*7 = 49

8*8 = 64

9*9 = 81

10*10 = 100

14*14 = 196

15*15 = 225

18*18 = 324

The sum of the areas =

324+225+196+100+81+64+49+16+1

= 1056 units ^2

The sum of x and y is eleven, their difference is five, what is the value of x and y?
REY [17]

Answer:

x = 8

y = 3

Step-by-step explanation:

x + y = 11

x - y = 5                     Subtract

2x = 16

x = 16/2

x = 8

x + y = 11                   Substitute x = 8

8 + y = 11                  Subtract 8 from both sides

8-8+y =11-8

y = 3

Colin pays £766.45 a year on his car insurance.
aliina [53]

Answer:

£807.84

Step-by-step explanation:

Cost of Collins car insurance per year = £766.45

Percentage increase in price = 5.4%

How much does the insurance cost now?

Cost of the insurance now = £766.45 + 5.4% of £766.45

= 766.45 + 5.4/100(766.45)

= 766.45 + 0.054(766.45)

= 766.45 + 41.3883

= 807.8383

Cost of the insurance now = £807.84
