Step-by-step explanation:
PR=2(L+B)
54=2(X+5+X)
54=2(2X+5)
54=4X+10
54-10=4X
44=4X
X=44/4
X=11
Length=2x=2×11=22
Breath=x=11

Area of the rectangle = 176cm²
Step-by-step explanation:
Given:
• Perimeter of rectangle = 54cm
• Length is 5cm more than Breadth of rectangle
To Find:
• Area of rectangle
Solution:
• Let Breadth be b.
• As the length is 5cm more than the breadth, we get:
- Length = 5 + Breadth
- Length(l) = 5+b
Formula for Perimeter of rectangle,
- 2(l+b) = Perimeter(54 cm)
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
Solution:
⇒2(l+b) = 54
⇒2(5+b+b) = 54
⇒2(5+2b) = 54
⇒5+2b = 54/2
⇒5+2b = 27
⇒2b = 27-5
⇒2b = 22
⇒b = 11cm
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
Length:
⇒5+b
⇒5+11
⇒16cm
Thus, Area of rectangle:
⇒Area = l×b
⇒Area = 16×11
⇒Area = 176cm²
Hence,
Area of the rectangle = 176cm²
