Question

The area of a rectangle with length twice of breadth is 578sq meters. What is the length of that rectangle

Answer 1

Answer:

given

length = 2x breadth

area = 578 sq m

area = length × breadth

578 = 2 × breadth × ( breadth )

578 = 2× breadth × breadth

578 ÷2 = breadth ^2

289 = breadth ^2

breadth = 17 m

length = 2 × breadth

= 2× 17 = 34 m

Answer 2

Step-by-step explanation:

Let l is length and b is breadth of reactangle.

l=2b

Area of reactangle=l×b

578=2b×b

578=2b^2

578/2=b^2

289=b^2

b^2=17^2

b=17 m

l=2b

l=2×17

l=34 m

Therefore,the length of that rectangle is 34 meter.
