Question

the perimeter of a rectangle is 40 m its length is 4 metre less than 5 times its breadth find the area of the rectangle

Answer 1

hi
let breadth = x

length = 5x - 4

perimeter = 2(l+ b)

2 ( 5x - 4 + x ) = 40

2 ( 6x - 4 ) = 40

12x - 8 = 40

12x = 40 + 8

12 x = 48

x = 48 / 12

x = 4

breadth = 4 m

length = 5* 4 - 4
20 - 4
16m

area = l* b

16 * 4

64m^2
