the perimeter of a rectangle and a square are equal. if the side of the square is 8 cm and length of rectangle is 12cm, find the breadth of the rectangle.
Answers
Answer:
breadth = 6cm
Step-by-step explanation:
perimeter of square = s+ s+ s+s
= 8+8+8+8
= 32cm
Perimeter of rectangle = Perimeter of square
Perimeter of rectangle= 2(l+b)
=2(12+b) = 32
=24+2b = 32
b = 32-24/2
= 12/2 = 6cm

Answer:
Breadth of rectangle = 4cm
Step-by-step explanation:
Side of square = 8cm
Length of rectangle = 12cm
Breadth of rectangle = ?
Perimeter of rectangle = Perimeter of square
Perimeter of square = 4S
= 4 × 8
= 32cm,,
Perimeter of rectangle = 2(l + b)
=> 32cm = 2(12 + b)
=> 32/2 = 12 + b
=> 16 = 12 + b
=> 16 - 12 = b
=> b = 4,,
