Question

a rectangle the breadth is half of the length and its perimeter is 180 then breath into length​

Answer 1

Answer:

1976

Step-by-step explanation:

Let the length of the rectangle be=l

So, breadth is b=l−14

Perimetre= 2(l+b)=2(l+l−14)=180 cm

⟹4l−28=180cm

⟹l=52cm

And, b=52−14=38cm

Hence, Area=l×b=52×38=1976cm

Answer 2

Answer:

72 UNIT²

Step-by-step explanation:

LET BREATDH BE B

THEREFORE LENGTH=2B

THEREFORE 2(B+2B)=180

2B+4B=180

THEREFORE 6B=180

B=6

THEREFORE LENGTH=12

THEREFORE BREADTH INTO LENGTH=12×6

=72
