The perimeter of a rectangle garden is 54yd. One side has a length of 15 yd. Find the area of the garden.

Lelechka [254]

Answer:

=》Area = 180 sq.yd

Step-by-step explanation:

perimeter = 2l + 2b

where, we have l = 15

so (2×15) + 2b = 54
30 + 2b = 54
2b = 24
b = 12

now, Area = l × b = 12 × 15 = 180 sq.yd

Use the quadratic formula to solve. Round to the nearest tenth if necessary.<br> 2x^2 -3x -7 = 0

abruzzese [7]

The quadratic formula is:

$\frac{-b + \sqrt{b^2 - 4ac} }{2a}$ and $\frac{-b - \sqrt{b^2 - 4ac} }{2a}$

In this case, a = 2, b = -3, and c = -7

So, we can plug in the numbers to get:

$\frac{-(-3) + \sqrt{(-3)^2 - 4(2)(-7)} }{2(2)}$ and $\frac{-(-3) - \sqrt{(-3)^2 - 4(2)(-7)} }{2(2)}$

Simplifying, we get:

$\frac{3 + \sqrt{65} }{4}$ and $\frac{3 - \sqrt{65} }{4}$

You need to use a calculator to find what these would be in decimal form. The answer, rounded to the nearest tenth, is: x = 2.8, x = -1.3
