Question

find the perimeter of the rectangles 1) Rectangle ABCD. Length=15 cm and breadth=13cm​

Answer 1

Answer:

56 cm

Step-by-step explanation:

because 13+13+15+15=56

Answer 2

Answer:

In a rectangle we know that two opposite sides are equal. So, PQ = SR and PS = QR

If PS = l and PQ = b

Perimeter of the rectangle = PQ + QR + RS + SP

                                      = b +l + b + l

                                      = 2b +2l

Again,  

ABCD is a rectangle. We know that the opposite sides of a rectangle are equal.

Step-by-step explanation:

Perimeter = 2(length + breadth)

              = 2 × (4.5 m + 1.5 m)

              = 2 × 6 m

              = 12 m

Therefore, the perimeter is 12 m.
