At the market, 5 light bulbs cost $9. How much do 7 light bulbs cost?
Rudiy27
Hello!

To solve this, find the cost of a single light bulb first, by dividing 9 / 5.

9 / 5 ==> 1.80

One light bulb is $1.80

Now, multiply 1.80 by 7.

1.80 * 7 = 12.6

7 light bulbs cost $12.6

Hope this helps! ☺♥

Thepotemich [5.8K]

We have composite shape consisting of two rectangles with dimensions of one rectangle as 20 feet by (10-6) feet and other rectangle as 6 feet by (20-17) feet.

We know the formula for area of rectangle is given as follows :-

Area of Rectangle = Length x Width

First rectangle's area would be = 20 feet x 4 feet = 80 square feet.

Second rectangle's area would be = 6 feet x 3 feet = 18 square feet.

Area of the room = First rectangle's area + Second rectangle's area.

Area of the room = 80 + 18 = 98 square feet.

Hence, final answer is 98 square feet.
