PLEASE HELP!!!!!! The length of a rectangle is three times its width. If the perimeter of the rectangle is 56 cm, find its area.
Alexus [3.1K]

Step-by-step explanation:

l = length

w = width

l = 3w

perimeter p = 2l + 2w = 56

using the identity of the first equation

p = 2(3w) + 2w = 56

6w + 2w = 56

8w = 56

w = 7 cm

l = 3w = 3×7 = 21 cm

so, the area is

l×w = 21×7 = 147 cm²

Help. I’m confused on this question and would like an answer. Thanks.
ikadub [295]

Answer:

Angle

Step-by-step explanation:

Since, the figure is in the final step of construction. So, it will have only two rays which as we can see are emerging from a common point.

So, it represents an angle.

An angle has two rays arising out of a common vertex point.
