Question

5. The length and breadth of a rectangle are in the ratio of 5:2 and its perimeter 18 980
cm. Find the area of the rectangle.​

Answer 1

Answer:

let length be 5x and brradth be 2x

perimeter= 2(l+b)

980 =2(5x+2x)

980 =2×7x

980 =14x

x =980/14

x =70cm

length =350cm

breadth =140cm

area =l×b

=49000cm
