Lena wants to replace a glass window in her restaurant. The window is in the shape of a square. Its side lengths are 7 feet. Suppose glass costs $7 for each square foot. How much will the glass cost to replace the window?

Step-by-step explanation:

It helps to draw a picture but also write what you are given

The square measures 7ft on all sides

youre paying by the square foot

to get square feet, use L x W

so 7ft x 7ft = 49 ft^2

so if we are charged $7 for 1 ft^2, then you add $7, 49 times

So youd write and solve

7 + 7 + 7 + 7 +... + 7 = $7 x 49ft^2

answer: do you still need this?

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.
