Question

The length of a rectangle is twice .its breadth its perimeter is 42cm. find its length and breath. let the breath of the rectangle be x the length of a rectangle =____. the perimeter is 42cm therefore the equation is 2(_____+______)=perimeter of rectangle therefore 2(2x+_____)=42cm. 2x ____=42. therefore _____=42. therefore x ______ upon ______. therefore x=______. therefore the breadth of rectangle =______ cm. therefore the length of rectangle =_______ cm​

Answer 1

Answer:

Step-by-step explanation:

let breadth be x

length=2x

perimeter=2(2x+x)=6x

6x=42

x=7

so length will be 14

breadth will be 7
