Terry had a square patio. after expanding the length by 20 ft and the width by 10 ft, the area was 999 ft2 . what was the original area?

The area of the original square patio will be 289 ft²

Explanation

Suppose, the side length of the original square patio is ft.

So, the area of the square patio will be: ft²

After expanding the length by 20 ft and the width by 10 ft, the new length will be: and the new width will be:

As the formula for area is and the area is given as 999 ft² , so the equation will be......

Using zero-product property, we will get.....

(Negative value of x is ignores as the side length can't be in negative)

So, the area of the original square patio will be:

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
