Question

the perimeter of a rectangle is 30 m and the ratio between length and breadth is 7:3 find the area of rectangle ​

Answer 1

Answer:

length=10.5. breadth=4.5

Explanation:

p=2(l+b)

Answer 2

Explanation:

perimeter of the rectangle=30m

ratio of length:breadth=7:3

let the common factor be x

perimeter of a rectangle = 2(l+b)

=2(7x+3x)=30

=>20x=30....x=1.5

:. length = 7*1.5=10.5m

breadth=3*1.5= 4.5m

area =l*b

=10.5*4.5

=47.25m
