Length of the rectangle is 8 units
Step-by-step explanation:
Area of the rectangle = 48 units
Length = x + 2
⇒ Area = Length × Breadth
48 = x (x + 2)
48 = x² + 2x
x² + 2x - 48 = 0
x² + 8x - 6x + 48 = 0 (Product Sum rule to factorise)
x(x + 8) - 6(x + 8) = 0
(x - 6)(x + 8) = 0
⇒ x = 6, -8 (negative value is neglected)
∴ x = 6
x + 2 = 8
Answer:
w >= 1.7
fyi the >= mean less than or equal to
d = 28
r = 14
r² = 196
C = 87.92
Given:
To find diameter:
d = 2r
d = 2(14)
To find r²:
14²
196
Circumference:
C = 2πr
C = 2(3.14)(14)
