Question

the perimeter of a rectangle is 260 CM. if the breath of the rectangle is 40 . find the length of the rectangle and also find area ​

Answer 1

Answer:

Length is 90 cm

Step-by-step explanation:

Perimeter of rectangle = 2 ( Length + Breath)

 260 = 2 (Length+ 40)

Length +40 = 260/2

Length = 130 - 40

Length = 90

Answer 2

Step-by-step explanation:

Let the length of Rectangle =x cm

Perimeter of Rectangle = 2×(L+B)

260 = 2×( x+ 40)

260/2=x+40

130=x+40

130-40=x

x=90 cm Ans

Area= L×B

=90×40

=3600 cm² Ans
