Question

perimeter of a rectangle is 80 cm and its breadth is 16 cm find its length​

Answer 1

Answer:

Length =24cm

Step-by-step explanation:

Take P to represent perimeter

Perimeter =2(length +width)

P=2(l+w)

80cm=2(l+16cm)80cm=2l+32cm

Bring the like terms together by transferring 32cm to the other side

Note that the + sign changes to - sign

80cm - 32cm=2l

48cm=2l

Divide both sides by 2 to remain with l alone

24cm =L
