a wire is in the shape of a of a square of side =12cmif the wire is the rebent into a rectangle of length 14 cm find its breaths which enclose more area
Answers
Answer:
9cm
Step-by-step explanation:
Perimeter of the square = 4× side
=> 4×12
= 48 cm
As the wire is bent into rectangle having length 15 cm
Since Perimeter of square = Perimeter of rectangle
48= 2(l+b)
24= 15+b
b= 24-15
=9cm
TOTAL LENGTH OF THE WIRE = PERIMETER OF THE
SQUARE
= SIDE × 4
= ( 12 × 4 ) cm
= 48 cm
LENGTH OF THE RECTANGULAR WIRE = 14 cm
BREADTH OF THE RECTANGULAR WIRE = P/2 - length
= (48/2 - 14)cm
= 10cm.
