Question

the perimeter of a rectangle is 720cm. Find its length if its breadth is 150 cm​

Answer 1

Answer:

210 cm

Step-by-step explanation:

Perimeter = 2 (L+B)

Or, L = P/2 - B

Or, L = 720 cm / 2 - 150 cm

= 360 cm - 150 cm

= 210 cm.

Answer 2

Answer:

The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle.

perimeter=L+L+b+b

=2L+2b

• L=?

• B= 150 cm

• Perimeter=720 cm

•°• 2L= P-2b

= 720-(150+150)

= 720-300

= 420

•°•2L=420

•°•. L= 420/2

•°• L=210 cm
