Question

. 2 A square and a rectangular rectangle has same perimeter if side of a squaro f 12cm and length of rectangle 16cm find the area of the rectangle.​

Answer 1

Answer:

perimeter of square = perimeter of rectangle

so 4× side= 2× length+ breadth

4×12=2× 16 + b

48 = 2×16 + b

48÷2=16+b

24=16+b

24-16=8

so length and breadth are known clearly

so area of rectangle = l×b

16×8=128
