Answer 1

ANSWER:

ANSWER:126 cm

ANSWER:126 cmSTEP-BY-STEP

ANSWER:126 cmSTEP-BY-STEPPerimeter of a rectangle = 2 (1+b)

ANSWER:126 cmSTEP-BY-STEPPerimeter of a rectangle = 2 (1+b)Area of rectangle = 1 x b Given that, Area = 650 cm² and Breadth = 13 cm

ANSWER:126 cmSTEP-BY-STEPPerimeter of a rectangle = 2 (1+b)Area of rectangle = 1 x b Given that, Area = 650 cm² and Breadth = 13 cm→ Length x Breadth = Area

ANSWER:126 cmSTEP-BY-STEPPerimeter of a rectangle = 2 (1+b)Area of rectangle = 1 x b Given that, Area = 650 cm² and Breadth = 13 cm→ Length x Breadth = AreaLength = Area / Breadth

ANSWER:126 cmSTEP-BY-STEPPerimeter of a rectangle = 2 (1+b)Area of rectangle = 1 x b Given that, Area = 650 cm² and Breadth = 13 cm→ Length x Breadth = AreaLength = Area / Breadth→ Length = 650/13 = 50 cm

ANSWER:126 cmSTEP-BY-STEPPerimeter of a rectangle = 2 (1+b)Area of rectangle = 1 x b Given that, Area = 650 cm² and Breadth = 13 cm→ Length x Breadth = AreaLength = Area / Breadth→ Length = 650/13 = 50 cmHence Length is 50 cm.

PLEASE MAKE ME BRAINLIST

Answer 2

650÷13=50cm

length=50cm

perimeter=2×(l+b)

2×(50+13)

2×63

126cm
