Question

The perimeter of a rectangle is 20 cm. The width of the rectangle is 4 cm. What is the area of the rectangle?
4 cm2
8 cm2
12 cm2
24 cm2

Answer 1

8

Answer 2

No, the length of the rectangle is not equal to its width.

Answer 3

So we have two widths of the rectangle, which means we will remove both the widths of the rectangle to find the two lengths...

= 20 - 4+4
= 20 - 8
= 12
Both lengths equal to 12cm, but we need only 1 length so we divide by two.
\[1 length = \frac{ 12 }{ 2 }\]
\[= 6\]

1 length of Rectangle = 6cm
1 width of Rectangle = 4cm

Area = 6x4
Area = 24 square cm [Answer]

Answer 4

4 = width

P = 2L +2W

20 = 2L + 8
12 = 2L
L = 6

Answer 5

A = L * W ,
A = 6 * 4
a = 24
