GIVEN:
Area of a square is same as that of a rectangle.
The side of the square = 12cm
Width of the rectangle = 9cm
TO FIND:
Length of the rectangle.
SOLUTION:
We know that,
Area of a square = side²
Area of a rectangle = length × breadth
According to the question,
Area of square = area of rectangle
Side × side = length × breadth
=> 12 × 12 = length × 9
=> 144 = length × 9
=> Length = 144/9
=> Length = 16cm
Therefore, the length of rectangle is 16cm.
Verified answer
Answer:
then area of rectangle is 12*12
=144
l*b=147
9*l=144
l=144/9
=16
