Question

The perimeter of a rectangle is 240 cm. If the breadth of the
rectangle is 40 cm. Find its length.​

Answer 1

Answer:

length of Rectangle = 80 cm

Step-by-step explanation:

let the length of Rectangle be x

Breadth of rectangle = 40 cm

perimeter of rectangle = 240 cm

2(l + b) = 240 cm

2 (x + 40 cm ) = 240 cm

2x + 80 cm = 240 cm

2x = 240 cm - 80 cm

2x = 160 cm

x = 160 cm /2

x = 80 cm

therefore, length of Rectangle = x = 80 cm

hope it helps you....

Answer 2

Answer:

Perimeter of rectangle is 240cm

2 ( l + b )= 240

2 ( l + 40 ) = 240

2l + 80 = 240

2l = 240 - 80

2l = 160

l = 160 /2

l = 80

80 cm is the length...mark me as a brainliest..follow me..thanks my all answers plzz
