Question

The length of a rectangle is two times its breadth. Its perimeter is 60 cm. If the breadth is x cm write an equation for the perimeter and solve to find the value of length and breadth. Pls ans only if you know..

Answer 1

Answer:

given

breadth=x

length= 2timesx

=2x

perimeter =60cm

2(l+b) =60cm

2(2x+x)=60cm

6x =60cm

x =10cm

x= breadth =10cm

2x=length =20cm

Answer 2

Answer:

Breadth=10cm & Length=20cm

Step by step explaination:

$let \: breadth = x \\ so \: length = 2x \\ atq \\ 2(2x + x) = 60 \\2 \times 3x = 60 \\ 6x = 60 \\ x = \frac{60}{6} \\ x = 10$
