Question

3. If A denotes area of a rectangle, I represents its length and b represents its breadth, find
(i) I, if A = 48 cm2 and b = 6 cm
(ii) b, if A = 88 m2 and I = 11 m
answer of no ,(i)8cm(ii)8m​

Answer 1

Answer:

\begin{gathered} {88}^{2} = {b}^{2} \times {11}^{2} \\ \\ = \frac{88}{11} = b \\ \\ = b = 8\end{gathered}

88

=

11

88

=b

=b=8

So, breadth = b= 8m

Answer 2

Step-by-step explanation:

area of rectangle=l*b

(i) 48 cm2 =l *6 cm

L =48 cm2/6cm

l = 8 cm

(ii) area of rectangle =l×b

88 m2 = 11 m ×b

88m2/11m = b

8m = b
