Area is Length x width:

(2x+5) * x = 420

Distributive property:

2x^2 +5x = 420

Subtract 420 from both sides:

2x^2 + 5x - 420 = 0

Using the quadratic formula:

a = 2, b = 5, c = -420:

-5 +/ √5^2 -4*(2*-420) / 2*2

x = 13.2951

Rounded to the nearest hundredth = 13.30 inches.

Assoli18 [71]

Answer:

other parallel side is 23m

Step-by-step explanation:

Let's assume other parallel sides as 'x'

One of the parallel sides of the trapezium plot measure 18m

so, y=18

distance between the two parallel sides measure 20m

so, h=20

now, we can use area of trapezium formula

A=\frac{1}{2}\times h \times (x+y)

now, we can plug values

A=\frac{1}{2}\times 20 \times (x+18)

we can set A=410

and then we can solve for x

410=\frac{1}{2}\times 20 \times (x+18)

10\left(x+18\right)=410

x+18=41

x=23

Hello!

To find the circumference of a circle you do 2 \pi r where r is the radius of the circle

So we do 2\pi 72

Then we substitute pi for 3.14

2 * 3.14 * 72 = 452.16 yds

Then we multiply this by 5 since he runs 5 laps

Which gives us the answer of 2260.8 yds

Hope this helps!
