let length = x
width is 7 feet less than length
width = x-7
area = length *width
area = x(x-7)
170=x²-7x
x²-7x-170=0
x²-17x+10x-170=0
x(x-17)+10(x-17)=0
(x-17)(x+10)=0
x=17 or x=-10
since length cannot be negative so x=17
and width =x-7 =17-7=10
length =17 feet and width =10 feet
<span>you can solve all quadratic equations using this method:
---
x^2 + 4x + 4 = 0

Answer with Step-by-step explanation:
We are given that
a.
b.Radius=2.58 cm
Substitute the values in the formula and 
Hence, the area of circle =20.9 square cm
c.Area of circle=1530 square cm
Hence, the radius of circle=22.07 cm
c.Area of circle of radius 15.2 cm=
Area of circle of radius 15.1 cm=
Hence, the area of circle whose radius is 15.2 cm is greater than the area of circle of radius 15.1 cm by 9.52 square cm .
