Question

e. The perimeter of a rectangle is numerically equal to its area. If the width of
rectangle is 11 / 4cm, then its length is-
i. 11 / 3 cm
ii. 22 / 3 cm
iii. 11 cm
iv. 10 cm​

Answer 1

Answer:

P =A

2(l+b) =l×b

2(x+11/4) = x× 11/4

2x+22/4 = 11/4 x

2x- 4/11 x = 22/4

22x - 4x/11 =22/4

18x/11 =22/4

x =22/4×11 /18

x = 9

Answer 2

Answer:

ii) 22/3

Step-by-step explanation:

perimeter of rectangle = 2(l+b)

area of rectangle = l×b

2(l+b) = l×b

2(l + 11/4) = l× 11/4

2l + 22l/4 = 11l/4

2l - 11l/4 = -11/2

3l/4 = 11/2

l= 22/3...
