A rectangle has a width of 2cm and a perimeter of 25cm. Find the length and the area .
Gwar [14]

2w + 2l = 25

2 * 2 + 2l = 25

<em><u>Simplfiy.</u></em>

4 + 2l = 25

<em><u>Subtract 4 from both sides.</u></em>

2l = 21

<em><u>Divide both sides by 2.</u></em>

l = 10.5

Now that we have the value of l, we can find the area.

A = lw

A = 10.5 * 2

A = 21.

The length is 10.5cm.

The area of the rectangle is 21cm^2

galina1969 [7]

Answer:

2m wide

Step-by-step explanation:

a=lw

15\frac{1}{2} =7\frac{3}{4} w

\frac{31}{2} =\frac{31}{4} w

w=\frac{\frac{31}{2} }{\frac{31}{4} } =\frac{(31)(4)}{(31)(2)} =2

wide = 2m

Hope this helps

In circle J with m/HJK 126 and HJ = 14 units, find the length of arc HK.
Tresset [83]

The length of arc HK is 30.8 units

<h3>What is the length of arc?</h3>

The length of the arc is defined as the distance between two points on the arc on the circumference.

Length of arc = θ/360 x 2πr

where, r is the radius of arc and θ is the angle formed by the arc at the center.

Given, circle J with ∠HJK = 126° and HJ = 14 units'

Plug, the values, we get

length of arc = 126°/360° x 2π x 14 units

length of arc = 30.8 units

Thus, the length of arc HK is 30.8 units.
