Answer:
l = 12 cm
perimeter = 34 cm
perimeter of a rectangle = 2(l+b)
34 =2(12+b)
17 = 12 + b
b = 17-12
b = 5 cm
area of rectangle = l×b
= 12×5
= 60 cm²

Answer:
Breadth = 10 cm
Area = 60 cm²
Step-by-step explanation:
Perimeter of the rectangle = 34 cm
Length of the rectangle = 12 cm
Perimeter = 2 ( L + B )
34 cm = 2 ( 12 cm + B )
34 cm ÷ 2 - 12 cm = B
17 cm - 12 cm = 5 cm = B
Area of the rectangle = L × B
= 12 cm × 5 cm
= 60 cm²
