The length of a rectangle is 2 cm more than the width. the perimeter is 20 cm. find the length and width.

Step-by-step explanation:

Let width = w

Length L = w + 2

Perimeter = 2(L + w)

20 = 2(w + 2 + w)

20 = 2(2w + 2)

20 = 4w + 4

4w = 20 - 4

4w = 16

w = 16/4

w = 4cm

Width = 4cm

Length = 4+2 = 6cm

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
