Question

the length of a rectangle is 3 more than its breadth . if perimeter is 42m , what is the length of the triangle​

Answer 1

Answer:

length of the RECTANGLE is 9+ 3= 12m

Step-by-step explanation:

let the breadth be x

therefore length= x+3

ATQ

2(l+b) = perimeter of rectangle

2(x+3+x) = 42

2(2x+3) =42

4x+6 = 42

4x = 36

x = 36/4

x = 9
