Question

a rectangle has perimeter 24 cm and length 9 cm find its breadth and area
​

Answer 1

Answer:

Formula for finding Perimeter of a Rectangle is following ;

Perimeter of rectangle = 2 X ( length + breadth ) ……….. ( A )

Given that,

Breadth of rectangle = 4 cm

Perimeter of rectangle = 24 cm

Let length of rectangle = y cm

Putting values of Perimeter and Breath in Equation ( A ), We get

24 = 2X(y+4)

24 = 2y+8

24 − 8 = 2y+8−8

16 = 2y

16 / 2 = 2y / 2

8 = y
