The area of a rectangle with perimeter 40cm is 75cmsquare .find the length and breath of the rectangle​

Answer»

ANSWER:

length is 15 cm and breadth is 5 cm.

Step-by-step EXPLANATION:

let length is X and breadth is y

then perimeter=40

2(x+y)=40

(x+y)=20

X=20-y

and area=75

x*y=75

(20-y)*y=75

y=5 or 15

and X= 15 or 5

but length is greater than breadth

therefore length is 15 cm and breadth is 5cm.
