Question

if the perimeters of a rectangle is 140cm and breadth of it is 3/4 of it's length what is the area of the rectangle?​

Answer 1

Answer:

1200cm²

Step-by-step explanation:

mark it brainliest

let length be x and thus breadth will be 3x/4

perimeter of rectangle = 2(l+b)

140=2(x+3x/4)

70=(4x+3x)/4

x=70*4/7

x=40cm

length is 40cm and breadth is 30 cm

thus area will be length*breadth

=30*40

=1200cm²
