Question

The length of rectangle is 40cm more than its breadth.if the perimeter is 120cm find its dimensions

Answer 1

Answer:

length is 50 &breadth =10

Step-by-step explanation:

length is x+40

breadth is x

perimeter of rectangle =2(length +breadth)

120=2(x+40+x)

120=2(2x+40)

120=4x+80

120-80=4x

40=4x

x=10

length is 10+40=50

breadth is 10
