Question

the area of a square of side 9 cm is the same as that of the rectangle of length 27 cm what is the breath of the rectangle​

Answer 1

Answer:

Step-by-step explanation:

Area of square= side x side

Area of square= 9 x 9 cm

Area of square= 81 cm2

Area of rectangle= 2(l+b)

81cm2= 2(27+b)

81 cm2= 54+2b

81-54=2b

27= 2b

13.5= b

Answer 2

Answer:

Breadth of rectangle is 3

Step-by-step explanation:

$\LARGE\fbox{According to question,}$

the area of a square of side 9 cm is the same as that of the rectangle

$\LARGE\fbox{Formula to find the breath of rectangle:-}$

area of square = area of rectangle

l×l=l×b

$\LARGE\fbox{Solving the question:-}$

Let b is the breadth of rectangle

we know that

area of square = area of rectangle

l×l=l×b

9×9=27×b

81=27b.

81/27=b

3=b

Hence the breadth of rectangle is 3
