Question

the length of a rectangle help is 5 more than its breadth if the perimeter of the hell is 74 cm find its length and

Answer 1

let the breadth of the rectangle be x and the length be 5+x
Now 2(l+b)=74
l+b=37
x+5+x=37
2x=37-5
×=32÷2
×=16

Answer 2

let breadht ..... b.... be "x".

length ..... is " x+5".

perimeter of rectangle = 2 × ( l + b )

74 = 2 × x + x+5
74 = 7+ 2x
67 = 2x
33.5 = x.

breadth = 33.5
length = 38.5
