Question

pls solve these questions:
1) given that m-17/2=2m-7. value of m?
2) the length of a rectangle is 13metre more than the breadth. if the perimeter of the rectangle is 126metre, then the length of the rectangle?

Answer 1

=) m-17/2=2m-7
m-2m=-7+17/2
-m=-14+17/2
-m=-3/2
m=3/2
therefore value of m is 3/2

2)Let the breadth be x and length be x+13
therefore, x+x+13=126
2x+13=126
2x=126-13
2x=113
x=56.5
therefore,length of rectangle=x+13=56.5+13=69.5m
