Question

If iys lenght is 11cm and perimeter is 44cm find its breadth and area

Answer 1

Answer:

perimeter=2(l+b)

44=2(11+b)

44=22+2b

44-22=2b

22=2b

b=11cm

area=l×b

=11×11

=121cm

Answer 2

Answer:

I suspect that the figure is square

$perimeter = 2(l + b) = 44cm \\ = 2(11 + b) = 44 \\ = 22 + 2b = 44 \\ 2b = 44 - 22 \\ 2b = 22 \\ b = \frac{22}{2 } \\ b = 11cm$

Hope it helps you
