Question

5) The length of a
rectangle is twice its
breadth .What is the
length if perimeter is
90 cm​

Answer 1

Answer:

45m=3W Divide each side by 3. 15m=W ANSWER 1: The breadth is 15 meters. The length is 30 meters

Answer 2

Step-by-step explanation:

given perimeter is 90cm

let breadth be X

so the length will be 2x

we know that perimeter of rectangle is 2(l+b)

2(2x+X)=90

4x+2x=90

6x=90

x=15

therefore length is 2x so, 2(15)=30cm
