Question

The perimeter of the rectangle is 40cm right the information in mathematical form using two variables.

Answer 1

Step-by-step explanation:

perimeter is 40

so , length and breadth are x

so., perimeter formula is 2(length + breadth)

so,.l and b are x

2(x+x)=40

so, 2 got left hand side it become 40÷2=20

(x+x)=20

x+x=2x

2x=20

x= 10

verifying the answer:

length =10

breadth=10

2(l+b)

2×10+10

2×20=40 so, the length and breadth are 10
