Question

the area of rectangle 36.and one side is dubbl of second side . perimeter of rectangle.​

Answer 1

Answer:

Area = l * b

36 = l * b

lb = 36

l = 36/b

b = 36/l

Find two numbers whose product is 36

Any of these pairs of dimension could be the sides of the rectangle: (36 and 1);

(18 and 2); (12 and 3); (9 and 4); (6 and 6); (14.4 and 2.5); (10 and 3.6); (8 and 4.5); etc.

Answer 2

Answer:

let the breadth of rectangle be x

length of the rectangle be 2x

area of rectangle =l×b

36=2x×x

36=2x^2

36÷2=x^2

18=x^2

x=√18

x=√2×3×3

x=3√2

length be 2×3√2

6√2

breadth =3√2

perimeter=2(l+b)

2(6√3+3√2)
