rate? in four years at simple 2. The area of square is 225cm². What is the length of e If (3.42)² = 11.70, then evaluate √11.70 and √0.117 Mohammed's flower garden is a square. If he enlarg 3m, the area will be 19m² more than the present area​

Answer 1

The current length of a side of Mohammed's square flower garden is
`\( (5)/(3) \)` meters. If he enlarges it by 3 meters, the new area will be 19 square meters more than the current area.

Let x be the current length of a side of Mohammed's square flower garden. The current area is
`\( x^2 \).`

If he enlarges it by 3 meters, the new length of a side will be x + 3, and the new area will be
`\( (x + 3)^2 \).`

According to the given information, the new area is 19 square meters more than the current area:

`\[ (x + 3)^2 = x^2 + 19 \]`

Expand and simplify the equation:

`\[ x^2 + 6x + 9 = x^2 + 19 \]`

Subtract
`\( x^2 \)` from both sides:

6x + 9 = 19

Subtract 9 from both sides:

6x = 10

Divide by 6:

`\[ x = (10)/(6) \]`

Simplify the fraction:

`\[ x = (5)/(3) \]`

So, the current length of a side of Mohammed's square flower garden is
`\( (5)/(3) \)` meters.

The probable question may be:

Mohammed's flower garden is a square. If he enlarges 3m, the area will be 19m² more than the present area​. Find the length of the side.
