Question

The measuures of two adjaccent of a rectangle are in the ratio of 7:5,if the perimeter of the rectangle is 336 cm ,find its rea

Answer 1

Hope it will help...

Answer 2

hiii!!!

here's ur answer...

let the Length of the rectangle be 7x and breadth be 5x.

given the perimeter of the rectangle = 336m

therefore 2(l+b) = 336m

=> 2(7x+5x) = 336m

=> 2×12x = 336m

=> 12x = 336/2

=> 12x = 168

=> x = 168/12

=> x = 14m

hence, length of the rectangle = 7x

= 7×14

= 98m

breadth of the rectangle = 5x

= 5×14

= 70m

VERIFICATION:-

perimeter of rectangle = 2(l+b)

= 2(98+70)

= 2×168

= 336m

hence verified

now,

area of the rectangle = l×b

= 98×70

= 6860m²

hope this helps..!
