The perimeter of a rectangle is 30 cm and its length is x cm. Find its area in terms of x. step by step explanation.10 cm
Step-by-step explanation: let the length be x
perimeter = l × b = 30
x × 3 = 30 cm
3x = 30 cm
x= 30/3
x = 10 cm
length = x = 10 cm

The perimeter of a rectangle is 30 cm and its length is x cm. Find its area in terms of x. step by step explanation.10 cm
Step-by-step explanation: let the length be x
perimeter = l × b = 30
x × 3 = 30 cm
3x = 30 cm
x= 30/3
x = 10 cm
length = x = 10 cm
Answer:
If l denotes the length and b denotes the breadth of the rectangle, then the
Perimeter and Area of Rectangle

● Perimeter of the rectangle = 2(l + b) units
● Length of the rectangle = P2
- b units
● Breadth of the rectangle = P2
- l units
● Area of the rectangle = l × b sq. units.
● Length of the rectangle = Ab
units .
● Breadth of the rectangle = Al

● Diagonal of the rectangle = l2+b2−−−−−√
units
Let us consider a rectangle of length 'a' units and breadth 'b' units.
Perimeter of Rectangle
Therefore, perimeter of the rectangle ABCD
= (AB + BC + CD + DA) units
= (a + b + a + b) units
= (2a + 2b) units
= 2 (a + b) units
Therefore, perimeter of the rectangle = 2 (length + breadth) units
