Question

Find the length and breadth of a rectangle having perimeter 100 meter and area 525 square meters​

Answer 1

Answer:

Answer

A rectangle has perimeter 50 cm and area 150 cm^2. find the dimensions of the rectangle

***

let x=length of rectangle

let y= width of rectangle

..

Area = length*width=x*y=150

Perimeter= 2x+2y=50

x+y=25

y=25-x

x(25-x)=150

25x-x^2=150

x^2-25x+150=0

(x-10)(x-15)=0

x=10

or

x=15

ans:

length of rectangle=15 cm

width of rectangle =10 cm
