The perimeter of a rectangle field is 320cm. Find the breath if the length is 70cm

Answer 1

B = breadth

L = length

P = Perimeter

P = 2 L + 2 B

P = 2 ( L + B )

320 = 2 ( L + 70 )

Divide both sides by 2

160 = L + 70

Subtract 70 to both sides

90 = L

L = 90 cm

Answer 2

Sorry, my mistake.

That is correct answer.

B = breadth

L = length

P = Perimeter

P = 2 L + 2 B

P = 2 ( 70 + B )

320 = 2 ( 70 + B )

Divide both sides by 2

160 = 70 + B

Subtract 70 to both sides

90 = B

B = 90 cm
